The number of vines per villian increases by team size. On a team of 8, we had to clear 96 vines. On a team of 5, we only needed to clear 40 vines. Also, my team noticed that not all vines respawn. On our five man team, only 31 vines out of 40 respawned, despite a lengthy wait, (team wipe. We made the mistake of getting spread out and not clearing out all the CoT first.) Just make sure that you kill them quickly.
Our team of five (L25-27, 2 stalkers, 2 corruptors, and a mastermind), could not finish the respec trial because we couldn't kill the L29 AV, which is essentially a giant plant/thorns dominator. The AV was able to consistently two-shot my L26 corruptor in about 1-2 seconds from full health. It has a pretty nasty cone attack (fling thorns?) that hits for about 200 upfront damage with several additional 20 damage ticks of DoT damage, most or all of it toxic. It also uses an AoE immobilize, (root?).
Anyone have any tips on taking out the AV after taking out the vines?
