Just an idea for a champ ;)

I want to start by saying hi to all of you since i'm new in this forum but it has been a while since i play LoL. But now lets get to the most interesting part... I came up with an idea of a champ who can actually mutate under various circumstances, based more precisely on what surrounds you in the exact moment you are playing. One aspect i want to highlight is the adaptation of some passives ( ) that boost you based on how many people are fighting against you. Actually what if this brand (and i don't mean ) new champ could drastically change during different situations? For example, you are 1v1, the champ, based on his passive, gets a damage output boost and maybe some significant cdr, but his health, armor and magic resist decrease. Suddenly you get involved in a 5v1 ( yeah, most horrible sistuation), the champ, with a delay of 5 seconds (or just a lil bit less), changes becoming super tanky but decreasing enormously his damage output and his movement speed, becoming a kind of "war turtle". At last, considering a situation of total absence from teamfight or 1v1: the jungle. What if this champion could get increased movement speed and attack speed? Just to make some significant differences without ending on the opness cough cough. The main idea around this champ should be variety and consciousness of what situation you are going to face. I'll let the rest of the community to add whatever they want for this concept, i just hope you enjoyed this idea, and if this is somehow too similar to any exisisting champ ( , i fear), please, ignore this topic, my bad :'D. Thanks for your attention.
