I'm not saying there's no awareness required for wow. Just saying its more important in league due to having the exact same thing plus what your team mates are casting, plus your creeps, plus your enemies creeps. Tracking CDs in wow isn't exactly hard.
There are multiple choices but they are largely irrelevant. There is only one right way to reforge/gem enchant. And the majority of talents provide no choice. Unlike in league where various builds are viable.
Healers yes, and I'll give you that about chi/energy etc. But some classes require no tracking. Mages don't have to worry about mana for example.
Again, not saying teamwork in wow isnt important. Just saying its more important in league. In wow your team is as strong as the strongest player. In league your team is as strong as your weakest player.
Fair point. I'll give you that.
Going to add a few more points:
Have to know the position of each champ and where they fit into the composition.A mage is a mage. I know exactly what hes going to do, whereas Teemo can be anywhere doing anything pretty much.
Have to be more flexible. You can't all be an ad carry, you can't all be mid lane, you can't all be Teemo etc.
More variety of matches in League. Never played the same game twice even against the same people/champions. Wows alot more rigid.
Map objectives. Various buffs, npcs,etc.
Counter picking/ being counter picked. (Ties into flexible point)
Less about FotM. Various champs banned due to balance.
Need to know when to fight, when to run, when to farm, when to team up, when to push and when to recall. In wow you only need to know when to fight and play offensive/defensive.
No addons to help.
Whats more complex; having to learn (random numbers here) 20 abilities or having to learn 4 abilities,a passive and 15 items (stats,auras,actives,everything)? What league lacks in ability bloat it makes up for it in terms of items/everything else I've mentioned. Your right in what your saying about wow requiring more mental maths but it's not about which game has more abilities its about so much more than that.(Points I've mentioned)
Again, Wow looks deep and is deep. League looks shallow and is deeper. There is probably a better way of saying that.
