Absolute skills

Actually, I wasn't discussing whether a hero will reach the endgame or not, and I'm not arguing that it won't happen in multiplayer. However, a hero with the "Special Ability" (SA) skill is better than almost any other upgrade. SA isn't a monotonous upgrade; it does take up 3 out of 5 skill slots, but 2 slots remain. If you get Logistics, you can also upgrade Defense. There are still 3 skill slots left, so you can upgrade those. Again, I'm not claiming that it's worth doing in multiplayer. Of course, in multiplayer, skills are needed now and today, not at level 25. The question is, are there no mentors on multiplayer maps? Or is it really the case that in 90 out of 100 cases, a hero doesn't reach level 20?
