Back in iCBT2. Most parties who are waiting outside dungeons and parties roaming in grinding areas are mostly looking for healers/tanks with Peltasta C1. Even though, IMO, a party of five only needs one healer, most parties still found it hard to find one.
What do you think? Will that also happen in OBT?

Clerics are pretty strong right now, so I expect to see lots of them in OBT. Probably more than in iCBT2.
Maybe Clerics will be the 3rd most played class (lots of people will still have biases against Clerics - thinking they are only for support)?
But you can never have too many Clerics in a party, so until Clerics outnumber every other class 3-1, there will be a shortage. 
That’s going to be one of the major issues, a lot of clerics are hellbent on avoiding damage entirely.
Granted for pvp that’s usually fine, as clerics struggle to hit enemies with most of their dmg options. But for pve it tends to do more harm then good.
Esp with the “put 1 krivis in there” fad we got going on.
Aside of that chaplain/plague doctors are known to be op in pvp due to ktos, so we’ll see some of those at least.
And we’ll likely see 1 cleric max per party in difficult content, considering how low our dps is vs groups and how effective full support wizards are.
So i think it’s quite unlikely we’ll run out of clerics.
No idea why. Buff cap has been increased so much that if you want krivis you better have 10+ buffs or be taking it for zabais.
