Oh trust me even geared players do struggle there too, the spiders are even more tankier than the boss. After wave 10 I had a pt of 2 solid rogs, we killed spiders at the very last sec literary. So feel proud of making it to wave 5, nothing wrong with that. I feel some tweak are still nessesary. Even tho I don't expect people to make it high on waves it would be nice if we stand a chance to at least wave 25.
