THE +1 SUIT EXP+ wrong or unfair

[Beautifulshow]

the exp+ 15% when normal suit using
but EXP+10% when the +1 suit using

is this normal ?

can fix the +1 suit for 15% or more

i think +1 suit much worth paying , every stat be better then the normal1 , so if i suit when i go Lvlup , i`ll lost 5% if i got normal suit ~

ye, it was always like that.
some stats are different between +1 and normal suite.
