I'm not saying Warlock Punch combos or is it useful, I said it was a rarely used move. Also, it was used as a combo finisher. There was a video from a while back where Falco dAir'ed to Falcon Punch. He missed and got a stomped by a ganon to Warlock Punch. Its these moments where it makes rarely used moves look good. In short, we don't need to make rarely used moves from Melee characters anymore useful.
And also, you've been suggesting many things which was unnecessary. You even suggested Ganon having projectiles in place of his Warlock Punch in the past, if I remembered it correctly, which is kind of stupid. Might as well give everyone a projectile over their useless move then.
What I'm also saying is Melee characters should have as little altered as possible as long they stay true to what they were (I'm not a fan of adding super armour, heavy armour, etc. I rather just have a simple "buff" or "nerf" but I'm not the one editing). For Brawl, we can do whatever we want to the characters since we don't have a starting point for them.
