I used to use assault grenadiers quite often but I have stopped using them completely as I found pretty much every opponent I beat s message me "Pay to win noob" which made me feel like I was cheating or taking an easy route to victory.
What are peoples thoughts on this?
For me, it doesn't matter.
Of course some people knows how to play better with them than others. One game I have had where I stood no chance against them, really good playing from my opponent. Maybe it was also bad play from me.
Yesterday I faced two players with those and they didn't matter. I try to read the game and do few things differently if I see them early.
Never have I actually complained at the chat to my opponent against his gamestyle.
