Imagine, Twyrfher, there's a worm sprite before the plophole. I'm not sure, you can plop your opponent's worm, through that sprite, to the hole, with Bazooka. Actually you are right about how often do you need. Also you are right, Petrol is tactic, but you could agree with me, that it can ruin a game. There are always new situations where you need to do your best, and there will be always new situations. You don't even know, when will you need that Fire Punch (and it can cause you will say : "Oh f@#!, no Fire Punches in crates, f@#! you, asdasdsadas, huashua).
P.S: Oh and by the way, if my opponent doesn't want to play with infinite Bazooka?
