heirloom make no difference to advanced players,
because every serious and competitive player will have +7 to head,chest(gloves) and optional to the leg.
of course there are exceptions, there are players that dont give a damm to heirloom and play very well.
Also the heirloom system would be completely removed that people would continue to play in cRPG as usual, the system is just illusion, because in the end everyone will have the same bonus. The heirloom system is just a grind to people play from level 1 several times again for people that choose that.
Of course with the small increase in the upkeep in the last patches, it forces people to retire because they want to have one more level of protection paying less compared to veterans players have enough looms and money to play and do not care about it.
The best would be just revamp the heirloom system and create a system where players would customize items and make sense to fullfill what cRPG is different from native the possiblity to customize your build, but also to customize your items.
Every gear would be allowed to have max 6 heirloom points, you could end distribute points to speed,damage,lenght,difficult,weight.
So a sword of war for example would be have several different combinations
(+3 speed , +3 damage)
(+3 damage, +3 lenght)
(+2 speed,+2 damage,+2 lenght)
(-3 to weight,-3 dificult)
or even a (+4 to damage, or speed,lenght, with the sacrifice of other 3 points)
also halving the experience points from 1-31 to be at 4 million points would not increase the time to have a unique and different item from others players. I think would boost again cRPG.
