Meh, I could still take or leave them. They were mostly added as a weak crutch to help low-sustain junglers and immobile junglers. And they did a bit, but it's not as if they don't work on mobile junglers too, so... it didn't shift the balance of the game or anything. It just gave a get-outta dumb situations free card to a lot of people. Sure, the blast plant helps me as often as it steals a kill for me, but in either case it's rewarding a player for being foolish by letting him get away with it through dumb luck.
That's still not really a good thing, I'd say.
