A lot of people seem to disagree with my previous post. I'm curious to see if any of the aforementioned soldiers who stuck with the stock RL says why he did so. I'm pretty sure I've heard Mike, B4nny and TLR already say something along the lines that they're already pretty good with it and the change wasn't worth it.

Maybe I got downfragged due to my DM comment. I said that as a justification as to why they might of thought the adaptation wasn't worth it. On the Original side you have Rando, Blaze and Seagull, ok, but using the RL are Mike, Tek, SDB, B4nny, TLR, Plat, Kaptain, Zebbosai... All some of the most experienced, top team, famous for DM soldiers of the game.
Edit: just remembered another MGE comp beast also uses the stock, Ma3la.
