i think the number if ice veins is fair they need them to be in high demand because they are needed to make higher level gear if they were really easy to get they would be to cheap and gear value would go down
Yeah there always seems to be a roving player that perpetually mines ice and gold ore. Its not very fun being level 60 and in competition with players that move and mine faster than you. It would be nice if the mining system was better balanced for crowded servers.
I think the main problem is that tons of gold and ice are needed for t4 AND t5. Maybe mix up the recipes a bit? Also, gold ore chunks should be breakable, or there should be an alternate recipe that uses them to make frostite.
