literally nothing changed. they were limited to +20 even before and as unreachable was anything beyond +10 it still is.
1st of all before wasn't limited to +20 was unlimited... 2nd you are talking about something that you have no clue about how is going to be for us at least. Maybe we will have enough tries thru events, maybe there will never ever be something in shop which would help you to achieve a better chance to upgrade this weapon and we will have in game ways only to get these stones. This crying is advance is literally hilarious... wait to see how is going to be, what is going to happen, bring constructive ideas instead of using a full box of napkins before you can even see the update on live servers. Ultimately, even if hard or unreachable... how will be for you might be for the others too so then again what's the problem again? Jeez...
