so, specifically, the complaint is that stun on the labs is too strong. seems reasonable. So lets have a look at the game where BH abused this mechanic to get a brutal domination, despite not playing seriously at all.
sadly he plays only one game with lab spam so thats all we have from him on this topic but lets take a look at that one at least.
so watching the replay at minute 7, BHs base looks like this:
meanwhile this is moraxes.
i admit that im not an expert at playing the game, but i think that if one side has 11 factories for spam and the other has 4 (1 for each team is making engies)
then one player will have more spam. I will need to ask a few 2k players to check but thats just my humble opinion for now.
Next, we take a look at what the whole map looks like:
appears to me that morax has a bit fewer land units there. Blackheart has 80 labs at this moment (2400 mass) while Morax has 16 tanks, 4 arty, and 5 scouts. (2000 mass worth of everything, of which 1200 is his land units)
Again, not an expert here but if you have 80vs20, that means its on average 4 labs vs 1 tank, and i think they might just be able to handle one.
for context, congreve and the mighty highlander have 32 and 39 land units, respectively. so you could say that the mighty highlander is trying hard to outspam congreve here; indeed, he is ahead on mass income, with 29 vs congreves 23. very formidable.
now, lets fast forward just 50 seconds in this action packed game to the following situation:
here we see BH and highlander expertly outmaneuvering moraxes upgrading acu, defended by all of 10 tanks, and flanking the right flanking labs with 6 more.
while blackheart has 52 in the immediate vicinity, and exactly 50 more stuck behind his acu. presumably hes microing them to bump it towards morax faster. simply astounding gameplay.
of course lets not forget highlander whos moving in with 24 strikers of his own, in a perfect example of high level teamplay.
Now, lets just pause for a moment and consider the unthinkable - what if BHs 52 labs were tanks?
Of course he was clearly building them for the extreme speed and micro benefits, but if he spent that mass on tanks he would have 28 of them. Now again, not an expert here but i do believe that 28 + 25 tanks are able to kill an acu. I'll confirm this with the top winter duel players as soon as possible.
but of course building anything but labs here would have been a mistake, and BH always plays super seriously and never makes those. so the labs were clearly used to stun the enemy army (of 10 tanks) before it ever had a chance to respond!
now, just 25 seat shaking seconds later, at 8:15 in the replay, the results of this epic battle (still in progress!) are as follows:
Morax has taken heavy damage, having lost 8 tanks, but he has gained 18 kills in those short seconds, possibly due to the part where labs have 100 hp. cant confirm, will need to sandbox. Morax has also lost around 2000hp on his acu, leaving 8000 left
Blackheart has lost 40 of his 50 labs that were there at the time! How could this happen? well 18 were ravenously downed by morax himself, 20 were killed by his valiant land army, and the rest were utterly destroyed by moraxes hidden bombers, sharing 12 kills between them!
Note that Highlanders tanks are still alive and well, but congreve is moving in as well! how exciting!
shortly afterwards, the epic battle concludes, but BH DID manage to stun a couple of t1 tanks. No really, i checked! they were indeed stunned!
fast forwarding a little more, we come to this epic engagement, with morax still on 8k hp, this time with 62 kills and blackheart himself moving in bravely with some labs in tow! lets not forget the overall situation, both players have added 2 factories each to their land spamming, morax on now on 6, and BH on 13 (again not including the engy facs) also highlander expertly snipes moraxes bomber squad. important detail here.
by just before 10 minutes the epic finale is starting to brew, with both morax and BH on 6.5k hp and BH bringing in 34 more labs, having kept them safely stuck in his base for later.
so to sum up the situation, morax has 8 tanks nearby, congreve helping out with 1 more and TWO arty, and BH has 35 labs, with highlander bringing in TWO tanks and THREE arty! Very intense! Both morax and congreve have a bomber each, and morax is bringing in a second. here, morax is deciding to run for the safety of his 4 mexes instead of trying to get to the beach.
mere moments later, we discover that morax is all alone, and facing BH + 17 labs, so while morax is shooting the labs, and gets his second vet, all of the mighty dps of BHs acu is crashing onto morax, his mexes seemingly reluctant to help! Likewise his bombers are focusing on the labs, and BHs acu is hardly recieving any damage!
and it continues! morax and the bombers are focusing on the labs, while they and BHs acu are bringing down his hp!
and thats when morax hatches a genius plan and DISTRACTS BH with a PD! BH stops shooting at morax with 700 hp and focuses on the pd instead! the pd is finished and BHs labs have sadly been out of range most of the time, not to mention that the stuns dont work on the acu! must have been a misreading of the eq changelog, surely if BH had known this he would have attacked the acu earlier instead of the pd!
At this point the game is in a solid draw territory, even now, both morax and BH choose to not attack the acus instead focusing on more labs, and the pd respectively.
congreve goes on to beat highlander against all odds. what a game, showcasing exactly how strong cybran lab stun is, were it not for that, things would have turned out entirely differently!
