sorry hon, hoof said no to this 10 years ago, nothing will change his mind I'm afraid.
He said no to PvP protection as well and look where we're at!
I already posted about this before long time ago and was regretted due to possible abuse issues
I've always liked to know how this can be abused? Frankly, this idea would promote PvP, maybe that's why it's been opposed so far. The decision to keep the PvP averse players' risk to being offended at a minimum is a weak one. There are numerous ways to set this up so that it could NOT be abused. It's the same fearful rational that was made when the Stomper achievement was introduced - only BB and Ladder attacks counted after a mere 24 hours. A quick example to avoid abuse here would be to make any xp gain minimal compared to xp gained from game critters. The BB works as the deterrent. Comparable reasoning asks, who still levels off normal critters when champions give 2-3x more xp for the same stam expenditure? Players seek the most efficient way to use stam, don't they?
I don't buy that this decision is final from Hoof. The game is always evolving. Players feel this idea can be abused because they see blatant solicitations in bios to trade 10 stam Prestige hits and Hoof decided this game abuse is acceptable. He could plug the loophole if he wanted but appeasement prevails.
I'd like to see Hoof spend time developing game aspects, like this suggestion, which have been neglected since the bitterly received Seasonal fiasco. He's spending resources on attracting new players by adding a mobile platform while the loyal game base is left wanting. How long I wonder??
