Please bring back tanks and ghost.

Essentially tank items keep getting nerfed (price goes up, stats go down.etc) while assassins, mages and adc's are gaining more and more tools to destroy tanks. Armor pen, true damage, health percent damage, lethality.etc The only tanks worth playing are juggernauts or dueling champions (who build damage not tank items) or else you literally melt. And the subject of ghost why would riot completely destroy the summoner spell. Why not just increase the 180 sec cool down or reduce the movement speed. Or reduce the cool down on the 300 cd flash. Why keep nerfing tanks, buffing all other roles, and destroy a viable summoner that isnt flash.
