What Riot is doing is:
A) creating a team play environment. Where your team needs to have the capability to cover for Kindred's short comings. Imagine a Thresh who saves his knock back and ult to push enemies outside of the aura and then traps them from getting back in or neutralizing a divers engage, essentially cutting their front line from the rest of the team. Just Imagine Thresh, Galio, Vayne, Xin etc. etc.
B) Deciding to tighten up on reigns of where a champion can be (See
) You are going to start seeing champs like Morde being tailored to a specific lane while weak in others. In Contrast champions who can multi-lane will be relatively weaker to a single lane counterpart.
Kindred's Ult is like Morde's Dragon when its on the map everybody wants it friend or foe. When the enemy see's Kindred's ult its going to be like Wal-Mart on Black Friday everyone wants in. Your job is to coordinate and punish the enemy team when they try to get in.
One situation is that you cast Ult everyone starts whacking at everyone but saves their ult if they can and then push the enemy out of the circle prior to the heal. I can see interesting combinations with
as his Ult steals %HP and heals himself for 100% of the DMG.
This way he can freely crush an opponent with his Q have enough time for another potential Q except he saves the last hit until after everyone is healed. Cast Ult to basically remove the enemies healed health and finish them off getting the kill and a double heal not including if he casts his W.
But I think good play around Kindred's Ult is baiting your enemy to use their ult and saving yours while doing enough damage so that you can nuke them after the heal.
