During endless archiv there comes a point where enemies dish out so much damage that not even a full tank can survive it without Magma Shell. This is the main reason why 90% of the top-end leaderboards currently feature at least one dragon knight inside. However, is that really needed? How about increasing damage dealt until cycle 6-7 or something like that and then only increasing health points. That way other builds could shine as well because it is really sad to see that to get high in Leaderboards only 2 classes really pack the punch.
