Common responses from the playerbase: skill issue, build issue, etc. While the game clearly has a balancing issue (which is fair considering its not at v1.0 yet). Bosses should not outregenerate your damage. 90% of the playerbase is playing the same build.
Its just not fun following a particular guide just to play with the highest efficiency possible. What makes videogames fun to me (especially action rpgs) is the ability to make my own build.
Its also the reason why I do not play any multi-player games anymore. There are barely people who play for fun, everyone just wants to win win win.
