To be fair, Zentor said "spend more time", not money.
My bad, my eyes were full of tears and I couldn't read very well :'(
I fix my answer, then:
my Sylphi was ready 3 days after release...2 months passed(Sylphi's release was on the 26th of december). I have had Sylphi ready for 54 days on a max of 57. How have they spent more time with Sylphi than me? Do 3 days on 57 matter THAT much?
FYI: on Firehawk's release everyone in these old server used to use Firehawk, while everyone kept saying it was easy to counter; same happened with Sagar's, Solomon's, Li Twins's, Lumos's and Zem's releases. These hero kept being into top 10-20 teams in the oldest servers for long time. Were/are they OP? Maybe Zem...what about the others?
This shows how your proves mean nothing.
Sylphi is OP into PvE (and she needs a nerf there); in PvP she gets melted by the right team...I'm sorry if you haven't found a way to beat her after all your struggle and other servers watching.
PS: my Sylphi and some of the Sylphi's teams I have tested are/were full equip, enchant and academy. The only missing things are 4 stars. If there is no way to counter 7* Sylphi, I don't know...maybe. Are you facing 7* Sylphi everywhere?
