I read ~10 pages or so of Icedreamer's post and it looked like discussion of the othuum had ceased... my apologies if they continued. Someone mentioned that a nice idea would be to think of the role that we want the othuum to play and then build statistics to help it match that role. There are a lot of potential valid proposals, but this is just the vision that I have of a unit that would in my humble opinion increase faction diversity and fit with the design of the unit. One difficulty in this is even though the Percival already behaves a lot like I at least would imagine a tank would... it has such high HP and low manueverability for a bot, when one would imagine a bot would sacrifice toughness and/or firepower for maneuverability. The Mongoose and hoplite vs. rhino and obsidian and pillar feel very right. Then on t3 it weirdly flips. But, I'll still make a proposal not touching the percy.
Looking at the design of the unit, the Othuum is a big, fat, tank... subtitled a siege tank. Most of its dps should be focused on its main gun with the large barrel, which should be its primary weapon. Right now that gun's dps quarter of a percy shot. I'd propose that gun is buffed to 800 damage per shot with a 1.5 Aoe. Also, perhaps more controversially, I'd like to see the range increased. The idea of a siege tank sounds like something that can outrange most any unit... putting bases etc. under siege and forcing things to come to them. I'd propose the range of this gun be increased to 37. A siege tank should outrange an armored assault bot...
The other gun, the machine gun, is generally for taking out smaller units. I'd propose that this be the secondary gun, and if possible target units independently of the main gun, at least if the main gun's target is outside of range, if that's possible. The dps of each gun could be cut in half, so that they total 150 instead of being 150 a piece.
Tanks can generally take a punch better than bots, so I'd like to see the HP increased to 10,000 hp.
Finally, I would consider nerfing the turn rate. This is a big cumbersome tank, why should it be better at turning than the percival? I like the speed where it is, however, once it gets a rumbling it should go.
We've clearly designed a unit that's a lot more effective than it was previously. That said, these stats befit a siege tank. It engages at longer ranges than bots of its tech level... the shot still does less damage, but the percival is so crazy that there's nothing we can do about that. It has machine guns to deal with lower tech units that get in close to it, but these aren't its main guns, like a real tank. In terms of balance, it will almost definitely still lose to percivals or bricks in an even numbers fight, by a landslide unless the percies/bricks are grouped up. The othuum would have about the same health and same range on its main gun, but about half of its dps would be wasted unless the fight got to close quarters. This gives the othuum a different role... it's more effective against a mixed army trying to surround it. It goes along with the Seraphim ideal of less variety of units, but units that can be a jack of all trades. Cybran/UEF (in theory) choose a loyalist/titan to fight t1/t2, and a percy/brick to fight t3. But Seraphim has the Othuum that can deal with any situation, but loses in a straight up fight to the percies, which specialize in killing high tech units.
The cost could be balanced as we see the unit in action. Compared to a percie, it has 10,000 hp instead of 9,300, 350 dps instead of 400, and some of its dps has 2 higher range and some has 10 lower. It has 2.5 speed instead of 2. I'd tentatively price it at around ~1200 mass.
Thanks for reading! Let me know what you think about the othuum or if there are other design proposals out there. Normally, I'm all for steady, small nerfs with each patch, but this unit's stats are very counterintuitive. When introducing new players to the game, they see the siege tank roll in and see the percie and just assume the siege tank is the big beefy unit and the percie is a cheaper, more maneuverable one. This change would alleviate that and make the game more elegant while not messing with the general balance (percies are the best).
