They are everywhere now and they do the same exact crap over and over again. Just run and dash attack or grab. If you grab, down throw to up aerial. Falcon Kick when you see someone roll and try to finish someone off with a Raptor Boost. Hell, I've had one match where I was at a high percent of damage and he kept trying to finish me off with Raptor Boost and completely failed.
I see him a lot too. A lot of them love to use Flame Choke to down tilt.
I still see him often in For Glory, but not as much as before. He does the same stuff that many Little Macs do and most of them are pretty pathetic. I haven't encountered any Little Macs that have use Jolt Haymaker off the stage.
I hate fighting Link because they mainly do the same annoying crap all the time, thus making these battles very boring and repetitive. Just spam the hell out of Bow and Boomerang, barely do any sword play, and finish people off with a side smash, up smash, or dash attack.
Spam PK Fire and PK Thunder and you'll do well with Ness in For Glory! Oh! And grab! One back throw and you are practically guaranteed to die!
Most of them are a bit predictable with their down throw to fair combo. A lot of them use Burst Grenade too much as well.
Five quick steps to master Sonic! First, Spin Charge or Spin Dash. Second, jump and use an aerial attack like his up air, forward air, or back air. Third, you want to occasionally use the Homing Attack while in the air. Fourth, runaway. Fifth, repeat steps 1-4! It's the same battle over and over again.
Egg Throw and and his aerials make fighting Yoshi a nightmare. I cringe whenever I see Yoshi for this reason.
Despite being "top tier," I haven't seen many Diddy Kongs.
