Not in the slightest. The vast majority of folks use Swappers because they are just so relentlessly good, not because they actually enjoy them. I myself have several things to run instead of DracoRat but can’t because that thing is so vital to me staying in the Aviary.
Not all Swap-Ins are bad, I get it. Most are actually fine. But then you have stuff like an armor-piercing stun attack and it all goes to pot. S-I Dodge has saved my rear-end without being oppressive, same with S-I Distraction.
S-I Stun could probably use a buff just to keep it relevant in the face of the monstrosity that is Stunning Strike. Defense Shattering Strike I’m pretty uneasy about, however.
Savagery is okay enough, mostly due to the fact that DracoRat and GrinchRat aren’t mind-bogglingly good on their own. GrinchRat is literally just a stat stick, after all. Not to mention that Savagery gets hard-stopped by Dodge, Shields and armor.
But then you have Stunning Strike, which just gets a bit much. First: It renders S-I Stun redundant. Second: It’s primary users are really good, with one being an Apex with great moves and stats and the other being a Stat Stick with the one of the highest resistance counts in the entire freaking game.
We do not need more broken Swap-Ins. That would simply exacerbate the issue. Even if the users of said abilities are awful on their own.
