The "wild stars" combat reminds me of "Albion Online", I find this combat system interesting, but I don't find it a very challenging combat, despite being more fun than the traditional "tab target", for me the ideal would be a PVE type " Albion Online" where each monster has a different attack with different range and animations, it would be interesting if each class had a skill that gave x% of dodge or defense, this would already make combat more challenging and it would be possible to keep the "tab target" style " . For example, a mage casts a fire skill at me, so I use the defense skill and defend myself, or the dodge skill avoids some of the damage, but not completely.
I find tab target boring after a while also, but it can be improved, improving mobs mechanics, and skills cooldowns, that's why I suggest to every class having at least 1 skill of each type, evasion, dashes, blocks, cc, etc, so they feel more dynamic, but I strongly agree with you
