Since the pvp lvl range nerf, the number of bases hittable by max lvl people has decreased, its probably been suggested already but rescale everything that was 150-x to 175-x. This should bring back the balance and prevent factions that cant hold what was intended as top lvl range tower field by putting ql 150 CTs everywhere because thats the only thing they can defend, and have side xp reflect the real state of control of bases.
By losing theses bases this would lead to more tl7 pvp since they could have easy base to take down and everyone would be happy.
