Some people starting the game haven't played an MMO before or just aren't very good at buttons or rotations. I even see a lot of videos of people who have played MMOs before who can barely do their rotation right even though it's only 2-3 buttons.

That's why the slow build up of the skills over so many levels really helps ease people into what are some pretty lengthy rotations later on. For someone like yourself it may be boring at the early levels but it's helping people who are not like you, and that makes more people play the game overall.

The armory bonus doesn't really need increasing because leveling is easy in this game already.

I don't think the combat is really unfun at lower levels on an alt class. I like that when I leveled alt classes I was eased into the rotation such as positionals on a monk. One button isn't necessarily boring because that's what it's like to play a healer most of the time and they are still fun.

If you only have 2 buttons in Sastasha, be the best at pressing 2 buttons of anyone and make them count more than anyone else would. Sprint to your enemies so you can start using them right away, use them on an enemy that still has a lot of health left so they don't get wasted, use damage buffs right and make use of stuns so the healer doesn't need to heal.
