1) As a Whm you will be focus and die a lot (and be the cause of your team lost). Because you will start ungeared and unskilled, some people will kill you in less than 3s. Be prepared to this.

2) Survivability tools : sprint, control and positionning. Whm are really dependent of their control to survive (Sch are better at tanking damages). Healers can survive until limit break (and more) if you find the way to play them correctly.

3) Major treat you will have to face as Healer :
- Sleep : 30s/15s/7s. Totally gamebreaking in FF arena, you will have to find the best way to manage these phase when you and half of your team can be sleep.
- Burst machine : typically tank, you will have to find a way to survive to full buff tank stunning you and bursting you.

4) Queue : In solo you win more wolves mark/experiences but premade can be funnier and you can manage to take down more geared player. For the moment, queue are in a really bad state (PvP players stopped to play or are trying the new Pve), it's maybe not the best time to start PvP. Lvl 30 and 40 queue are easier to start with because the morale (pvp stat) is not taking into account in this mode (you can also twink your character for Lvl30/40 queue).
