Azirs W and Ult Questions

Hi, New to discussions sorry if i break any rules... Unfortunately I do not have a video-

Something with Azir's w I found was that sometimes after cast I could not auto attack unless I moved I do know how to recreate but happened several times, not sure of conditions but if i find it I will post link to video.

Although I usually move while summoning soldiers now to avoid this.

Main reason why i decided to show myself up was because of today, a Tristana prepping her rocket jump while I ulted her and she can jump over

even while she was in the air and I ulted, I thought nothing can over over Azir's walls?

There was one time the wall was completely finished and soldiers in place, the Tristana jumped right over it.

I've been playing Azir ever since i saw the marksman azir and was interested in how far it could go. Is this a bug or just me?

Players that witnessed it- http://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/1915430585/202620320 if it doesnt show- http://na.op.gg/summoner/userName=dontfocusmeplz I wont be playing anymore games just to be safe...so latest normal match...

Also, sometimes if the soldier is too far away but still up, [E] doesnt work and you end up standing still. Is this supposed to happen?

Pressing E without soldiers just stops you and says it consumes mp, but it does not. Is this also a bug?

When Soldiers are out of range for auto attack you cannot use e towards them? (near max range of soldiers being able to stay up)
