DAT WISP DOE.
So it is soul-crushing to play against because it can completely turn a game around?
No, it's soul-crushing to play against because it requires both teams to split up their forces and ruins the potential of team engagements. It is the opposite of "Roam as 5" strats intent on breaking the other side and clearing a path to rax. It is waiting slowly and steadily for the slightest of advantages to build over time due to a prolonged siege to turn the tide one way or another, meaning everything leading up to that point is mostly mindless PvE and fountain trips.
If it can so easily turn a game around what makes it not broken?
The thing is, it can't. Except in pubs, and not every pub-star Tinker/Furion can pull it off. It requires just as much discipline on the part of the split-pushing team as it does the defending team. The only difference is, a split-push teams knows exactly when they're split-pushing, and maybe even picked for it, but the defending team needs to react and adapt, and their current itemization might not survive a siege-y grindy games. That level of coordination is low in pubs, so when people turn around games by shifting to split-push, people go "OMG FUCK THIS WUSSY ASS SHIT."
Also what should I be using for my camera settings now that I'm not longer using WASD for camera and instead using my mouse?
Edge pan? That's pretty much it. I have mousewheel-click and mouse3 bound to Drag Camera, and it's occasionally useful, but it's but no means integral.
What you should be aiming for is to make your right hand as fast and accurate as possible. You want to:
1) Be able to view an area around your hero much larger than what the screen size is using edge panning. Something like 20-30% more. You want have the mouse capturing as much of the opponent's team as possible without obscuring your own hero. You should be constantly leading it ahead of where your hero is walking, occasionally snapping it behind or the sides to check for flanks. Don't make the mistake of keeping your hero in the center of your screen, unless you're in the very middle of a fight.
2) Use the minimap reflexively. If someone shows up on minimap, you need to be able to click it on the minimap to see what's going on. This can last anywhere from 1 second to 10 seconds of full vision. Regardless of how much they're derping into your wards, you want to look at them as fast as possible, check their items (for wards, gem, dust, BKB, Blink) , check what they're doing, and then return to your hero. Practice monitoring the minimap. Runes spawn? Check them (you can bind these but I don't). Someone roaming through jungle? Check river. People diving your teammates under tower? Check to see if a TP is worth it. Opposing TPs to tower? Check for number and capability and decide whether to go in or hold off.
3) You need to do all that while being able to aim your skills properly, particularly Blinks and skill shots like Arrow/Hookshot/Hook. You might not play these heroes, and that's okay, but being able to control the camera and aim your skills simultaneously is the ideal you're aiming for.
