Tile hits are unavoidable but core parts of this game. And there's not much one can do to avoid being tiled. 

To equalise it a bit my idea is to force attacker to stay on the hit tile for - let's say - 15 seconds. That will give person hit or other clan member reading battle reports to retaliate. Time have to be long enough to potentially allow attack BUT not too long, because excessive waiting time will kill tile hitting for small players (big guns will be sending full marches and waiting for retaliation).
