The mana block function was discussed in the Woolerton thread from the very beginning and therefore has been known (public) for quite a while and hence the sharp tone, asking for a buff before researching the hero is irresponsible:

Lady Woolerton - Mana Shield from Guvnor
Woolerton - Mana Shield (Titan)
@Zyx
You positioned yourself as an experienced player that DOES research and knows the hero cards and yet you don’t and didn’t.
I will grant you honesty, many would have quickly done a search on Woolerton, have confirmed the information and remained silent.
I find the forum is filled with requests for buffs and nerfs coming from people that do not understand the hero and this was a clear case of that.
I apologize for the harsh tone.
