ok, about Ling:
I agree, disbalance is smoothed by fact most of my server have her.
She is almost useless in arena and need some skill for other uses, it additionaly smoothes her disbalance.
Sylphi is good or OP all-around: HoL, Raid, CoF and even decent at arena. And at our server she is max 5* (only one), rest 3*, and not awakened. I don't want to think what will happen after, but what I hear: millions damage.
I still agree that at this moment she is absolutely unbeatable only at Legendary Kong. But what I hear from forum, situation will get worse.
No need to fix? maybe but that means in 3-4 months we should get few heroes who will make all older ones fully obsolete.
Goram, probably we have too little gorams (and I am one of owners, so my opinion is somewhat biased) but I did not notice dramatic change, comparing to time when first Sylphi s appeared.
Beating whales? Not on kong anymore for me, can't even get close
rest more adequate.
