Alright guys well it doesn't help the meta at all to be a bunch of negative nancies. Sure, this isn't really a tech, in the common sense of the word, but it can still prove to be a really useful strat in getting a tree out safely. Considering that there aren't many projectiles that can go through the tree (the only ones that I can think of right now are Mega Man's blades and leaf shield) and the rocket will absorb at least one aerial or projectile, the opponent is forced to approach from the ground. And if they want to get to you, they either have to roll through the tree, or attack with a ranged attack. The first one is easily dealt with, since USmash, DSmash, and UTilt are amazing for punishing rolls, and as for the second one, since the axe has a bit of range you can still chop at your tree while staying out of the attack's range.
While I agree that this probably wasn't deserving of its own thread, ganging up on the guy like this isn't doing us any favours.
