At 100+ level(12Sky2 Silver) grinding starts geting slower, so you will have teams in caves, no prob. And at level 112, lot players do not leave serpentines cave, because they have full teams there and do not want to leave.
That is not a good idea. You really should go grind to river map with team or not. Serpentines give like 0.001 per kill, muckers in river give 0.005 per kill and those other aggro mobs give 0.006 per kill(12sky2 Gold).
They want to kill, but even more time to kill you can at least 2x faster, team - 3 x cave is not huge faster, unless you just stand there chatting XD 105 rarely is good, but once you hit level(Twelvesky2 powerleveling) and using better sell 112-112 uniques, upgrade their course if have enough money in Twelvesky2, you can even try MATS in the past, because they are much easier to 60%. 105 rare attack weapon damage and few 777-96 ability damage atributes 844 us have perfect unique DMG and 113. We even estimated 105 60% + 4 aoe weapon damage reduction than 60% of 112 unique + 1 Twelve Sky2 Gold.
