So I spent some time doing some sandbox testing, in order to compare the efficacy of the T3 bots versus each other. The goal was to compare equivalent mass costs of bots. The testing consisted of the faster of the two bots marching in line abreast formation to the other army of bots, also positioned line abreast. I did not micro the bots. Also, I specifically avoided testing the Loyaltist EMP by making sure the Loyalists and the opposing bots got close enough to fire at each other, but not for the Loyalist death to stun them. Here is what I found:
Harbinger (12) vs Loyalist (21):
Harbinger won 7/7 matches, average of ~7 Harbs remaining
Harbinger (32) vs Brick (21):
Haringer won 7/7 matches, average of ~15 Harbs remaining
Harbinger (12) vs Titan (21):
Harbs won 7/7 matches, average of 9 Harbs remaining
Harbinger (32) vs Percival (21):
Percy won 5/5 matches, average of ~6 Percies remaining
Harbinger (20) vs Othuum (20):
Othuum won 3/4 matches, average of ~3 Othuum remaining
Loyalist (24) vs Brick (9):
Brick won 2/2, average 4 Bricks remaining
Loyalist (20) vs Titan (20):
Loyalist won 2/2 matches, average of 10 Loyalists remaining
Loyalist (24) vs Percival (9):
Percival won 3/3 matches, average of ~8 Percies remaining
Loyalist (21) vs Othuum (12):
Othuum won 2/2 matches,average of ~8 Othuum remaining
Brick (9) vs Titan (24):
Bricks won 3/3 matches, average of 4 Bricks remaining
Bricks (20) vs Percival (20):
Percival won 2/2 matches, average of 11 Percies remaining
Brick (21) vs Othuum (32):
Othuum won 3/3 matches, average of ~18 Othuum remaining
Titan (24) vs Percival (9):
Percy won 3/3 matches, average of ~6 Percies remaining
Titan (21) vs Othuum (12):
Othuum won 2/2 matches, average of 11 Othuum remaining
Percival (21) vs Othuum (32):
Othuum won 2/2 matches, average of 10 Othuum remaining
So the order of effectiveness of the T3 bots in these head on tests are Othuum>Percival>Harbinger>Brick>Loyalists>Titan
To be fair, since some have mentioned kiting Percies vs Othuum, I tested 21 Percies running away in formation from 32 Othuums following the Percies in formation, and Othuum lost badly, killing only 1 Percy. I was surprised Othum fared so well in these tests, whenever folks have been comparing T3 bots these days the Othuum seems to be considered the "forgotten" bot, omitted in many comparisons. Yet it does very well in fights with other T3 bopts based on equivalent mass costs.
