Different Combonations and a new Map idea

Ok so first of all I'd like to say hello. I'm Gerrant lvl 21 and I Main Amumu as a tank atm. It's my first post here. so HI! I also go by Amumu the Assassinator(His AP tho). How do you do?

now to the matter at hand I would like to bring up a couple character Idea's. I'm horrible at expanding upon things so I'll post it for those who can.

It'll go Pimary/Secondary

FIrst the Support/assassin. Extremely vague I know but Ii feel supports shouldget some kills too Not just stay in the back and cower behind their ADC.

Next is the Support/Marksman As I Said before, Supports shouldn't have to just sit back gain assists and heal.

the last is the Tank/Assassin Yeah this may seem op, matter of fact this is op so yeah. But to balance this it has to be AP or AD not both.

Anyways that is it. There are my 3 idea's don't criticize me, I know more people have thought about this but probably never posted it before. I just don;t want the next character to be a mage or another fighter. I'd rather it be a support or tank. Comments thoughts criticisms, jokes and all of the assortment are welcomed here.

The other thing I'd like to talk about is a new map. Asside from this one How great would it be to play on another map asside from the crystal scar and the others. I mean another Place instead of the regular Howling abyss map kinda seems been there done that but is a loved original map you can;t stop playing. So if you'r all in for a new Map say so here.
