towers, teleport & minions

Hey Riot,

i was playing a custom as Fiora with teleport and flash. My top lane pushed all way to the enemy inhibitor tower and i started teleporting to a siege minion that was attacking. The tower was attacking the siege i was teleporting to and we all know minions become invulnerable while being teleported to. Well i had my camera unlocked and realized that once i started to teleport to the siege minion the tower stopped attacking completely. It didn't switch targets or anything, it just stopped until the teleport was finished, then killed the minion. I understand it isn't the biggest issue in league at the moment but i thought that is a bit unfair, especially if an entire team took teleport the could just all teleport to one minion and stop the tower from attacking anything til they stop teleporting. Do you think there is a way to fix that?

Thanks, Concerned League player
