Control wards, traps, and teemo.

I'm curious as to why the design team decided to have the new Control ward be able to not only to see stealth traps; but also disable them entirely. From what I read in an article by Riot Colins he said it was to make a safe zone of sortsfor the user. This seems like it in the same design space as a sweeper from the sense of once you use sweeper any traps within the area were disabled for the duration of the sweeper. So I'm curious as to why the design team did something like this instead of just keeping the previous pink ward?

Also along the same vein I'm curious as to why all traps aren't created equal. For example, with Caitlyn's traps you aren't allowed to target them at all regardless if you have a sweeper on them or not. Would it be possible if when you used let's say this new control ward or the sweeper to allow you to attack those traps? Because the amount of zone control that they provide while the enemies cannot do anything about it besides just move around them. I might just be an idiot but any feedback concerning this would be amazing.

Lastly, would like to talk about this ward and that little bugger teemo. This ward seems to be indirectly nerfing him at the very least. For the previous pink wards to see the traps is fine, and for this to spot out the traps again is perfectly fine. That's great counterplay putting one down to snipe down those freaking shrooms so you can walk in for the kill. But the fact you can put one down in a bush in top lane to just disable the traps seems a bit skewed to the side that is attacking teemo. Now I haven't seen this ward in action or if it actually will just disable all of the shrooms teemo does set up. But if that is the case this is another item that forces teemo to not wanting to use his shrooms as much or make AP viable build. Like I said I don't mind for good counterplay, but when it concerns an ultimate ability that can be stopped for 50 gold,or a free item(scanner) that's when even I gotta feel bad for the little guy.

Thank you for your time reading this, would love any comments or discussion concerning this new ward and how it interacts with traps as a whole. :) ttfn
