big with elise in both human and spider form

as i have been playing elise for a while, i realised that there are important bugs that need to be fixed. firstly lets start with human form. i still cant do the flash e combo as my e always spawns behind me and doesnt work. now lets move on to the spider form, when you press e, most of the times it doesnt work for me, as i keep bashing e mid team fights to jump on the weak ad carry but it doesnt work even when walking around jungle clearing, it didnt only happen once, but many times so far. secondly sometimes when you e upwards you immediatly come down from the ability for some odd reason, jumping on wards doesnt work and jumping on minions doesnt work sometimes. anyone feels the same or had a similar experience?
