Switching MASTERIES Should be Free
I was just thinking about Masteries and after further thought. We should be able to switch masteries we have already paid for, for free, forever!
If we have already spent to unlock them, why can't we switch as needed so that we can get every edge we can get for each specific opponent we may face during a path. Would some mastery setups be more interesting? Maybe suggested masteries per opponent and per opponent in special quests with certain buffs. Etc.
A lot of game content could be built around this premis above. Think about it, we could move our Masteries around as needed for the (Nodes/Buffs/weird-stuff ^_^) your Devs think up, "as long as it's Skill based" and you wouldnt have to make ridiculous buffed nodes for Act 5.3/5.4.
Just throwing ideas out there...
