RE: New Legendary Summoner: Assumption

Immunity in my opinion is a very great ability especially in higher tiers where debuffing is the common gameplay, it might not sound especial if you only have 1 monster in your lineup that has Immunity but imagine everyone not being affected by negative buffs you don't have to worry about slow, demoralize, or headwinds, rust, and the list just go on with all the negative effects, you can use all your monsters in their maxed potential and it is not common in higher leagues, where everyone has debuffs. I would even say it would be fair to have it at 7 or 8 mana.
