He's still a semi-clone? Yeah, um, we knew that.
He's also number 32 on the current official tier list. Marth is 41 and Lucina is 47 respectively. Want to know why? Because it's worked on by professional players and analysists.
http://www.ssbwiki.com/Tier_List#Super_Smash_Bros._4_tier_list It's obvious why I trust this over what your post just said. You're literally giving a blind hate statement and providing zero reason to believe he's that bad. However, even more notably, that tier list is done by people who know the game very well and aren't providing objectively bad reasons for why a character is bad. You've given no explanation. Why should I take your argument here seriously?
Lucina is definitely worse as a Marth clone, where Roy very much is not at this point. Roy being hated for being a clone in Smash 4 is hypocritical because Lucina is objectively worse as a clone as well. Nobody is using Lucina as a scapegoat argument, but stating a fact here. Yes, she's worse. Objectively so in this game. She purposely has worse stats, a worse ability than Marth, less options than either Marth or Roy.
But that's not my entire point; There is no way Roy could ever be bottom 5 in this game when it's clear from a competitive stand point he has tons more options than someone like Ganondorf or even Palutena. And Lucina as well.
