For experienced player it can be easy in my opinion... You can buy good gear even if you wanna start new char you can easily be lvl max cuz you can buy good gear or someone/your friend can help to clear the map/boss (or someone that buy plat can just Lvl up to 75 by buying the Lvl up pack... And 75-81 will be easy for them... Like the people that reach to 81 in just a day during the expansion)

But for new player it will be a Lil bit hard cuz they have no idea what/how to do the quest + the map endgame (gy, fester and other) is pretty hard for the new player to break through without good gear......and also they don't usually have even enough gold to buy xp elix... I feel all this situation before when I first playing the game

I frequently saw some newbie begging in town to ask help them clearing some map for them... Not trying to look kind but sometimes I do help them but not all the time honestly cuz I have something else to do too...

This is just my opinion... Don't hate me XD
