Give Wolvers tracking again, and reduce their attack delay.
For Chromalisks, give them frontal shields, like Gremlin Mortafires.
Tier 2 Chromalisks should have a frontal shield that covers a 90 degree arc in front of their face. T3 Chromalisks should have this extended to 180.
Gremlin mortafires are one of the most IRRITATING LITTLE [censored] I have ever had the misfortune of killing.
They are probably the monsters I hate to fight the most. It's not that they're hard, it's just that their a pain and time consuming to kill.
Chromalisks are already annoying, maybe in higher tiers make the spit blob wider.
But +1 to wolver tracking.
