3. SLKR turned out to be a more solid pick. He ramps up Damage fast enought. Now the only problem is, if in later waves a B1 dodges the AOE for any reason, they will oneshot you.
Sounds like whether you use SLKR or Ventress that this is the time to pull out those much-maligned Acc mods. Not so much b/c one droid dodging ruins everything **during** a wave -- Ventress will gain TM from the other deaths and go again -- but rather that if she AoEs most of a group, then finishes off a straggler, then the next wave you're only starting with +35% bonus TM. If the B1s are gaining stats with every wave, then even starting at 35% TM they might outrace you to 100%. Accuracy mods fix the problem, although I suppose you could also use Talzin's mass AoE at the beginning of the next wave, which would cause another death from a massively-ramped Ventress, giving another +35%, and hopefully that 70% TM would be enough.
But still. Accuracy mods and a whole ton of ZA for this battle.
