Anivia Wall Change

Just a simple suggestion for Anivia's wall that would help her out but not take away who she is (high damage but with high mana cost, high cooldown times, and very low mobility). My suggestion would be to make it somewhat like Yasuo's wall where it can block abilities. However, each ability that hits the wall, reduces its uptime by 50% of the remaining time. If the wall has a 5 second uptime, the first ability to hit it (assuming it is hit as soon as it goes up, like to block a skillshot) drops its remaining uptime to 2.5 seconds.

Reasoning: This is a meta of hyper-mobile champions, a lot of which can simply use an ability to get past the wall (not to mention when it just bugs out and lets someone through anyway). By adding this, it helps her stay relevant in today's game instead of a rare, niche pick.
