PvP is not soo bad ... just in that early stage of the mod , combination of the "actually working" character teams are limited. Thats why most of people playing Samuro-Xyrella-Cariel or Orcs buff combos.
Im prty sure that in future updates Blizzard will increase amound of mercenaries and the situation will change.
There are some red flags for sure. We're mostly matched by character level (right?) but the main power component is the level of the skills and gear, while coins are gained randomly from packs. Maybe there is a point in going full lvl 1 to avoid fully upgraded opponents?
The game mode is new thou. I will hold onto my final verdict for now.
The devs made a whole post explaining the matchmaking in detail in case someone here is interested in it
My problem with their system is that it motivates players to NOT level up abilities they don't use in their PvP comp. It is common that you need only 2 out of 3 skills for your Merc.
Well, you also gain a small stat bonus if you max out everything about a merc, so that's something you want to do if you want to play with the best of the best. At a certain mmr you also can't be matched with a bot and will have to play against a high level oponent.
I mean the mode on PVE is fine, and honestly I think its even better for F2P players because its a challenge if you have everything by paying PVE is pointless. PVP on the other hand, its only for P2W for F2P players makes no sense.
