new player, trying to decide on class

[Estellios]

Just try all the ones you are interested in since you can play multiple, the game will be more fun that way anyways!

Play a bit further into the story (past the first 3 dungeons) and you get a quest in the Gridania Adventurer's guild that unlocks the Palace of the dead. The party composition doesn't matter so you should not have to wait long to enter no matter what job you are. The layout is random and you start at level 1 and level up very quickly. While this doesn't carry over into your actual level you can use this to get into the 20s or 30s in a class and feel how it plays with more of its abilities available. Best of all, if you clear 10 sets of floors you get a hefty chunk of xp towards your actual level so you can use it on occasion to level up your classes. Once you get past the Level 10 quest for your starting class you can unlock other classes and change between them at will so you don't have to worry about having to create a new character to try them all out.

I wouldn't let being a newbie prevent you from playing tanks. Lots of people take it as their first class and do just fine. Let people know you are knew and take the dungeons at a pace that is comfortable to you and be sure to ask questions and read what your abilities do.

And for your healer question, using a controller works just fine. Tons of people play on PS4 or with controllers on PC, myself included, and have no problems with any of the jobs. That said if you do think you would be more comfortable playing with a mouse and keyboard, you should be able to hook them up to the PS4 and use them. In fact it's recommended to at least use a keyboard for chatting since it's a lot faster and easier than using the virtual keyboard to type.
