I have seen that some abilities , important ones , are behind a paywall . Let me ilustrate this .
Everyone knows that healing is available since very begining in the game. But , yellow healing is behind a paywall. Yes , its subyugated to an epic event sheep.
Good luck getting one …if not you have to wait to pull Vivica … An slow hero that is not the jewel of the crown .
Another paywall yellow healer . Dalilah …
Mana block / Silence .
Another amazing ability reserved to Proteus, Hansel, Merlín, Peters , Hel…
Green attack Booster.
And this is the more disgusting of all… When you intended to at least release a decent green attack booster (on costume chamber ) you change it and made her a copy of Inari.
Green attack boosters behind the paywall
I hope SG balance this feature a little bit . Releasing a good healer in yellow or a decent green attack booster is not going to hurt you! …i think
