I like helping heroes , I don't think the requests are too demanding ,it's about luck on what they ask and sometimes is nice to have something not too easy to do.
But I agree that there should be a skip button, once a day, so u have one chance more to find a suitable quest.
And YeS , red , blue and shamans orcs(all ranged mobs) are usually at lvl 210+ and they are a pain in the ass , those should be lowered a bit or put in a map where you have a bit more of movements and you can actually lure them out of their big group. if u bring with u one of those items with special power they die easly but the damage they deal is unbearable.
suggestion for others , pull first all the other mobs from far away , usually those orcs are the group "guardians" and if you attack them first all the group will follow, u should try to leave them last and kill others before (dark and not ranged ones) but again , if u have no space to go... GL
