Again I'll say it in a way that you might be able to get through your head............YOU HAVE CHAMPS THAT ARE SET FOR ARENA........you even stated that you have +16 gear that is geared for arena. Even players that were in gold before now are stuck in silver, and that doesn't just happen over night.
A brand new or F2P player can not ever hope to get strong enough to beat you, because you are already geared out and someone new or F2P can not hope to ever get past you.
You said on this account you are F2P but guess what, im prerty sure your other accounts or main account isn't. Also you have time and experience so that counts for so very much.
If a new player just starting the game seen your team they wouldn't attempt to attack you because they know they would lose from the start. That is what you are not understanding or completely ignoring.
The problem isn't with the champs i got because my team is HK, Seeker, Warmaiden and Kael so yes i have the proper team and stuff but that doesn't change the fact that because of things like inactive teams dropping from gold to silver to bronze because plarium is to scared to remove them, just on the chance that they will come back to the game, so instead they just drop them in ranks and it takes months for them to be gone from arena if they ever get removed once they hit bronze.
That is the major problem with arena for new players, the fact that they can not hope to attack and win more then they are getting attacked and losing. I understand that its all about team work, but how can even the best team work help if you just can't hope to touch them.
