How has the lane meta not changed yet?
With how the new jungle is now I would have expected it to change by now. Junglers are easily soloing dragon pre-5 (and at a decent speed for that level) and dragon no longer grants global gold. The buffs are nice but until the 5th one it isn't as drastic toward the game.
Also seeing as how bruisers offer a good amount of dps and tankiness (let's just use garen for example) can offer a lot of help. I've also expected supports to start being in the mid lane with the ap mages and assassins and adcs having their own fun at top lane.
Top lane is usually considered the boring lane that nothing but farming goes on. (sounds a lot like adcs to me) in which they all have some form of mobility in their kits these days.
Mid lane is usually for assassins/ap mages which roam around the map to get fed off other lanes. (sounds a lot like a support roaming the map to get assist/help other lanes) where as mid lane is the easiest lane to do that with.
Jungle is well, jungle
Bot lane's usual only purpose for being where it is at the time is dragon control, but again junglers usually always deal with that themselves until about the 3rd drag(or if they get a kill bot and wanna fast take it) I can see bruisers/tanks helping more since if they bully someone out it'll be easier to take without much contesting (IF they need help)
This is just something i've been pondering on my mind. Just lookin for feedback
