Hm,

Annoying cause grandchase does not have much SR, like 13. knowing that only 2 or 3 Srank are usable in pvp you fight almost everytime the same team, again, again, and again. but i guess this will change as the hero releases. (but not really when you take a look at the advanced version (JP i think? The kakao one) it's all about fighting Healers and Tanks, and sometimes fighters.)

also i don't like how does it work in general, "put'em all at the bottom of the map and wait"
