sheer versatility of trundle's pillar makes him high skillcap
Erh... it doesn't seem that hard... I mean mostly people just use it as a knockup to delay the backline or to block a thin passage, or just to slow. It's really not that versatile, only with like 3 uses. And choosing one is also pretty simple.
garen's basic spells all have a condition to them so he has decision making and macro focus, using Q/W to minimize crowd control is harder than it looks, E has a mini-isolation mechanic to give you the most damage
W is just a timing spell, sure it doesn't last long but it's basically just a short shield. Just using it whenever he goes in would be fine.
Q timing is pretty obsolete because there's no way Garen will get in range without using it. Also, it's CD isn't that long so there's not usually a need to hold it - if you can stick to your target they'll only get 1.5 seconds of being able to use abilities.
E's isolation thing isn't really all that important since most people will either 1) fight him in minions, aka trading, or 2) know that they're strong enough to take him out so that it doesn't matter if he's getting the iso damage or not.
