No it actually is. I know some hardcore Starcraft players and they all click none stop, just to keep themselves on edge so they can react within 1/2 a second. They literally just never ever stop clicking as fast as possible.
I know a lot and they... don't do that? It's pretty wasteful outside the first few minutes of the game where literally almost nothing happens (your opponent literally can't get over to where you are with something that can kill you until you have at least 13 supply). They'll tap their keyboard a lot but there's an actual good reason for that, it's to be logistically efficient (checking production, that sorta thing). Which is the real reason why most people are just completely awful at RTSes when they think they're okay. In fact, I'll just go address another post to show this.
This game is intentionally locked in gaming medieval era, because the Korean competitive teams would go nuts otherwise.
SC2 is actually wildly less popular in Korea. For various reasons. Having like 1/10th the playerbase in PC cafes compared to LoL (generally labelled as the most casual MOBA) is probably the primary reason.
Limited 5 item queue? Check.
Like, the only scenario wherein a large queue makes sense is in the TA/SC context where spending is not frontloaded. I would actually argue any RTS where you have frontloaded spending and a large queue is BAD design because stuff sitting idle in queues is logistical inefficiency (which people are really bad at understanding I find) and you need to encourage people to increase their infrastructure. In general if you have more than a couple units in queue you could probably just build another production facility in the meantime and build stuff faster.
Stupid units needing of babysitting? Check.
Lot's of tactical abilities dependent on fast clicking? Check.
The actual biggest complaint from high level players is the ability to largely a-move to victory in WoL. In fact, it's generally agreed that unless you're in the top quarter or so of players, the easiest way to win is to do that and just be more logistically efficient. That being said, HOTS does have more tactical abilities. Whether they require a bunch of fast clicking is kinda subjective, though.
Inability to zoom? Check.
This is actually the one thing I really dislike about games with zoom. It's that they don't have a minimap. You can't keep track of the strategic situation at the same time that you're doing other stuff. Like, every single high level player in Starcraft will tell you they spend a lot of their time looking at the minimap (and the bottom third of the screen in general). It's really good at telling you "hey, look here, you're gonna die soon".
I mean, it looks really nice. But for me, I honestly give no ****s about that. SMAC and MOO2 have awful graphics by today's standards and they're still the 4X games I enjoy playing the most.
Lack of adjustable, advanced behaviors of units? Check.
An actual legitimate complaint here.
Edit: okay, I think I found the stray quote tag.
