The Legends PVE event is fun, but I think the available characters should be modernized

Some background if it matters(it doesn't), I played legends PVP religiously back in the day and have every feat related to it, it was pretty much all I did in the game at the time. I quit playing around 2014 and got back into the game a few months back. It's great seeing how this game evolved over time but legends feels jarringly outdated compared to the rest of the game.

I know it's not a very popular mode and investing in it would be seen as a waste of dev time, but this event has made it relevant for the short time being because of feats so I have some thoughts regardless. The obvious suggestion is to replace the character models with the newer ones but I assume there are technical issues in doing this or it would've been done already, plus I'd understand wanting to preserve the older models in some capacity. Regardless, what feels most awkward are the powersets that were given to the legends.

Not including skin variations, there are 39 characters for legends content(if I miscounted let me know). The 40th would've have been Gorilla Grodd but he didn't end up working out for whatever reason. A lot of the legends were released together as counterparts and as a result feel extremely similar with Kilowog and Arkillo being nearly identical. The issue is that so many of the legends have very stale movesets. I'm not doing the math on this, but at LEAST half of the characters have Swoop Attack, which in my opinion is the most boring ability in the game. The logic at the time might've been that swoop would've been a good gap closer without risking being blocked, but as of now it just takes up a precious skill slot on nearly every playable character. For Kryptonians I can kind of understand it, but it's even weirder on the lanterns. The mode could be spiced up by giving the legends new ability replacements to make them more unique across the board.

This is ignoring smaller issues such as Amon Sur having an absurdly long finisher that does hardly any damage, or Flash having a finisher which is a slow brawling animation that feels awkward on his character, or Superman being one of the weakest characters to this day for some reason, or legends pet damage not being scaled up for PVE content. Overall I just want to see my favorite mode refreshed. I totally understand that there are bigger priorities like episode content, but I think that if the x10 feat completion was made into a permanent thing then the mode would remain somewhat active. Legends used to be such a popular mode with characters being added every episode, the feats no longer being inhumane to achieve feels great and gives everyone a reason to play it again.
