Poll for the Strongest Individual Fighter. RW+WW (TOP 5) on LVP

even tho almost all of them reached their peak in uL.

Of course they would reach their peak while in uL. You dont quit a clan and then join another one to become less skillfull, specially not uL.
Those would still reach their peak if they joined another clan.
Same will happen if for example Jakez leaves uL, and join another serious clan. He will then become better than he was when he left uL.

So that is kinda irrelevant
