The AC2 also uses 2 tons less than an AC5 (25% less tons) and only 1 crit compared to 4 (75% less)
The AC5 does 5 damage per heat, the AC10 & AC20 to 3.33 damage per heat.
If you bring the heat to 0.6 (3.33 dph) from Live 1.0 (2.0 dph) or PTS4 0.8 (2.5 dph) that is a pretty good buff.
Bringing the heat to 0.5 or lower would start to make the AC2 the clear choice for brawling and sustained suppression.
