The games I played against you guys post 2.7 (Sorc/Merc) I felt were fairly competitive given that that was my first time queueing ranked on my sniper and mud was just teaching me the ropes of my role. Tbh I'm not sure why people cry about "tunneling" and "double" group compositions. Guard is the hinge for a teams defense, if the opposing teams tank is weak, it makes sense to focus your strategy around the tank. Me and itchy found double healer to counter tank tunnel and went on a 50+ game win streak. In the end, the teams that are the best are those that can adapt strategies into their comps, the ones that cry about strats will transfer servers to find ones with archaic strategies that they prefer or find a new game and move on. Either way, pot5 benefits from the people that stay to create a very competitive environment.
TL;DR: I didn't read anything in this thread and decided to take a wild guess on the topic
