For those who say its rough without a cleric it sure is. But luckily this game has hp potions. Your’re about to queue up for a dungeon with a random team comp and are just betting on a healer? Everyone with the exception of Clerics should carry hp and sp pots at all times. You’re gimping yourself and your party by not doing it. It’s like going into the fight without a weapon. Sure you can do it and it will be painful and take forever but you can do it nonetheless. But does that make it a good idea? Absolutely not. You’re gimping yourself by reducing your survivability.
Tanks who complain about their armor breaking too fast. This is common. Easy mending to this carry two sets of armor. This is coming from a high 232 pelt here. Carry two sets and save yourself and the group some trouble. If you want to be cheap then say brb after a mob. Go to character selection reselect your tank and log back in then repair your gear and reenter the dungeon. Plain and simple
In my experience of the game, my highest level 245, nothing is too difficult. Its a matter of trial and error, learning from your mistakes, figuring out ways around it and most of all preparation. You have squire and pardoner buffs, alchemist potions and barrier scrolls. Between these things you should be able to do pretty much any content without a healer or tank.
TLDR learn to be batman and be prepaired
