It’s very awkward trying to get the monster you want targeted and then keep it targeted. I’ve gotten the hand of holding down ctrl to lock targeting, but it just feels like a very backwards way to handle things. Targeting should be locked on the current targeted monster by default and only change if the player tabs or the monster gets out of range. This makes more sense because in most cases you want to focus one monster down at a time instead of firing randomly into a mob. This is especially annoying in boss fights, where it feels like summons exist just to make it hard to get targeting on the boss. Holding down ctrl makes it a little harder to use skills and the fact that you have to let ctrl go to tab to another monster is extremely annoying. It’s also much more likely for your finger to slip if you have to fight holding ctrl the entire battle.
Tabbing also doesn’t work well, the target circle seems to follow the least logical pattern when targeting monsters, so I’ve spent the first 10 seconds of some combats just tabbing around trying to get the right monster selected. This is probably not a big deal for mouse players, but for keyboard players it’s pretty unusable.
