Btw I would like to add a few notes for competitive players approaching arena.
First you need to ask yourself, are you competing for the overall top100 ranking? or are you competing to own 3 arena a day for maximum reward points.
If you're trying to boost your overall ranking, you find one arena which suits you very very well and take full advantage of it, even if there is already a player with a score you wont surpass there.
But if you're aiming to take over the arena, look for the ones where you have a shot of outscoring the rank1 and ignore the ones you cant.
How MH looks at Blitz:
I have a question. Is it true that the 2000 pts exchange for diao chan x 5 reward can only be claim once?
yes it is one time only deal, like a cheaper targeted harpy just for Diaochan (you are meant to buy 1x800, get her to slvl7+ with baby harpies and 1x2000 pretty much)

just have to comment that right now the rewards for holding an arena are so good that it is worth it to be a little spammy with the diamonds in order to conquer. I can't imagine that they won't reduce them at some point so i have been getting the rewards while i can. I am currently max leveling my entire inventory that i have never had a chance to do and i already have claimed most of the limited rewards including a max diachan etc. I even used all the mini madheads on urd because exp is so cheap. I will probably bank all the kfc's as the event come to an end so they are waiting for the next new cards.
