People are impatient and greedy. This is a new server, it was launched today. What did you expect? With 15 testers on beta huge problems can't be revealed. Balance problems can be revealed at mass pvps, where a specific class would always survive.
However we are trying to be as fast as we can, and you can't deny that, in order to fix all issues and make you able to enjoy a good gameplay. And what's the respond? 4-5 guys shouting phrases like 'close the server', 'fail balance' etc, without really having a clue of what they say or how hard we tried to achieve what is achieved till now (members that really helped by serious reports are always an exception).
In conclusion, what i am trying to say is that patience is the key. If you follow any server you will see that day by day the gameplay becomes bugless, funner and better.
Also about summoners, we are not planning to make them playable at pvps anytime soon, that's because it would take days in order to pick the right skills to be added/removed and the stats to enhance/nerf at pets.
