I feel depressed ( zz'rot portal feedback )
The game was feeling stale and boring to me until that new void item was released. 
It gave me a reason to play tanks again, playing around with it made me feel significant as a tank as I am able to take towers and pushing by being sneaky and clever with portal placement.
Patch 5.2 significantly nerfed the item. The defensive bonus now only applies to the 1st and 4th spawn each wave. What is worse is changing void spawn defensive stats from HP to armor. This is a big nerf because towers ignore targets' armor and so the voidspawns can't attack the inhibitor tier tower without a minion wave anymore. (It was already difficult to pull that off as you usually have to place the portal somewhere visible to let the spawns hit the tower & ADCs kill the gate in about 3 seconds --why can you crit the portal anyway, it should be coded as a tower--)
Not to mention the new AP -> damage on the portal. :(
It was a lot of fun to use, why kill it out of a sudden? It's not like people learned to play around it's mechanics in this short time from 5.1 -> 5.2 and it's not like there will be games without ADCs to kill the portal.
... Please highly consider reverting this change Riot guys... I loved this item a lot, it doesn't have to be super niche...
