We're not afraid of MP, we just don't care for it. The adolescent behavior alone is reason to avoid most MP centric games. I'm fine with the trashtalk; what bothers me more than anything else are the disconnects. I can put considerable time and effort into a game, and just when the tide turns in my favor, my opponent quits. This is especially true in any game with any sort of ranking system.
You mention a "skill jump". This is not a jump in skill, so much as technique. In any game, if you choose a certain character, and research a particular skillset, and equip your character with certain items, and play in such a way, you can win. This isn't learning a skillset, this is following a recipe. Boring. Many thousands of players have spent many thousands of hours playing this game in order to figure these things out.
Figure it out for yourself. Fly by the seat of your pants. You may not win, but I can pretty much guarentee that you will have more fun.
The two RTS games I have played the most multiplayer wise have been through third party ladders (clanwars for zh, iccup for starcraft) so i never really dealt with those issues at all (always a couple bad apples but that's when admins just ban em ). The length of a game is more a problem within just that game itself. I'm just not a fan of a game style like that where I need such a large time constraint, I like jumping on playing a few games and heading out. But that's pretty subjective since it's based on taste :/
I was more mentioning that to the genre of RTS sorry for the misconception . (Most team based games run through multiplayer have been quite terrible experiences for me like Left 4 Dead) There are many basic skills that you have to know to play RTS games well. Hotkeys, basic micro idealism, harrasment, economy management etc. For the genre of RTS single player is just a terrible medium of storytelling and gameplay. There are "fun" RTS campaigns but it's a very mediocre experience in comparison to the intensity of a game online when you are face to face playing someone else. And AI's are horribly predictable and can't micro lol So you are correct that in other genres there isn't really a skill jump. In an online FPS you can jump on and shoot shit and be fine.
