Why do most eso activities often feel so unrewarding? And how do you think it is possible to fix this?
i think one of the biggest problem is that there basically no long-term goals for veteran players to accomplish other than housing, fashion to lesser extend, achievements(rarely have interesting rewards) and sets sticker book(which is mostly pretty useless).
My idea would be to shamelessly steal guild war 2 world bosses, legendaries(that would work often as material sinks for not abundant resources) and generally update crafting system and saturate world with unique rewards and crafting materials that you can always sell. dynamic encounters are nice step in this directions but right now it is not enjoyable to do them.
But i guess it is probably already too late so it is just my rant. I just tried gw2(it has horizontal progression too) recently and it makes me sad and i can't unsee how many mmo aspects can be improved in eso(and i love tes lore).
