It seems like pump spells are just limited burn spells. They can't alternate between removal and burn like bolt and such can, and set you up for getting 2 for 1'd frequently. The damage payoff for using pump instead of burn doesn't seem significant either, at best a berserk will hit a thoctar, but will usually hit a 3 or 4 power goyf or nacactl, which isn't much different from bolting their face. Using a non-berserk pump spell to have your kird ape kill their goyf seems good, but you'll find yourself wanting to bolt their confidant, painter, your own guy against ichorid, damaging ad nauseum players, etc etc more often that you'll get away with trading giant growths for tarmogoyfs.
