Just needs some upscaling.
They're GOOD raids. the issues are just that they're old and need some love. Syrcus needs the impact of it's mechanics to actually HURT. If people stack those stack markers on the last boss there should be a wipe not little boo boos. Lab needs an update so that team C isn't useless. Seriously...if you go in there on Team C...you are completely shafted in there, second boss you won't even participate....
World of Darkness....same deal, make the mechanics punish people for ignoring them. Toss some nice glam items into the loot table and they would really be worth it and more fun.
Really, another quality of life thing they could do is expand the Limited leveling roulette button you can click in duty finder settings to include raids...offer better incentives for max level players to que without it to keep the pool of players good. everybody wins.
