You are writing a lot of things that are just plain not true.

For one getting a BtE off is a joke, its literally as simple as popping all of your damage CDs (and unlike the tribind fester, it is very responsive) and just hitting bind + BtE. It is so reliable that I don't hesitate doing it on focused targets, because I can hit them both at the same time and it's good enough for the server. Same goes for stun gun.

A lot of your grievances seem like "git gud" issues, somebody not within LoS? Stunning a DR'ed target? Not being able to pull off melee LB? Ricochet hitting more than 1 target because somebody walked in (it's an instant off the freaking GCD)? I'm also not sure whats unconventional/situational about blowing all your cooldowns and hitting a damage button? Does that mean Berserk+Fel Cleave is situational? I just hit it whenever it's up and it works fine (I use the word fine when it doesn't crit =p).
