Each has their own playstyle and none are really worst than the others. If you think LLC is the worst. Kleese would beg to differ when he’s sitting near his rifts, almost immortal and killing you with math, even though he has no idea what it does. Giving everyone free shields for days. And he says it best, he may be old, he may be miserable, but he’s alive.
And as for ISIC, have you ever seen someone shred a sentry faster than ISIC in his Ult? If you reach level 10 as ISIC and pick the right helixes, and your teams still lose in Incursion. Honestly, I don’t know how that happens, it’s an anomaly.
El Dragon is the weakest link in LLC everyone else is amazing if done right. But as for LLC being the worst, you must not know how to use them right, And Marquis may have low damage on his gun, but the predatory strikes are nasty to go up against when they target sooner, cloaked and leaves behind an area of effect. Have three placed near you, and when a character comes up close to kill you, they will be in for a big surprise.
And UPR does have Oscar Mike who is an Attacker, who sucks at defending. If you’re an Oscar Mike playing defense, you’re Mike-ing wrong. And the also have Ghalt, who is also an Attacker. If he pulls you into his team, onto a trap, you’ll probably end up dead. He is also a beast up close with that shotgun of his unless you have a good escape ability, not on cooldown, you’ll probably end up dead most of the time, unless that Ghalt aims at the sky. Even then, he’ll kill you with Ghalt magic, cause Ghalt.
Maybe if we did get the faction wars game mode, it could force you into the Factions you don’t appreciate enough. If you need any advice on how to turn any character into a walking death machine, I’m sure there are guides on the forums, or you could always ask. Take it from me, I used to think the LLC were the worst too, but now I understand just how wrong I was.
Maybe they aren’t your type of characters, but until you really try to good with them, you’ll never know. I had no idea how much I would love a character like Ambra, but once I started trying to do good with her, she was the first character I mastered. And only mastered the others just to find more characters that I like.
Sorry for the long post, I would give you a cookie, but your shirt doesn’t appear to be tucked in. So sorry.
