Add Flow of Battle to Avvar.
This.
I also second the sugetions for the assassin regarding moving KitS and IWNH closer to the start of the stealth tree, levelling her is such a chore.
The assassin is intended to be a high risk, high reward mêlée single target burst damage character.
The high risk is there. Sure, stealth sheds aggro, but if a marksman saw you go into stealth while aiming, they can track you. Archers and horrors can also sometimes randomly target you while you're stealthed even if you entered stealth out of LoS. Add in enemy AoE and odd melee hit boxes, and venatori mine spam, all of which heavily limit your movement. Given the spawn points all over the map, it's very easy to get knocked out of stealth and left trapped in the open. This also completely gimps damage output which relies a lot on KitS for us underpromoted scrubs. High risk, all well and good. I approve of this, actually.
However, the reward is underwhelming. In NM, there are far too many high priority units and high HP and armour units for her to be of much use. Sure, she can burst down one pride demon or venatori mage, but what about the other 3, and the hundreds of despair demons or spellbinders?
Her spike damage is closely linked to auto-crit from stealth. Adding mark of death would help with bosses, but do little to alleviate the general inability to kill the vast number of high priority targets wandering around.
I would suggest losing poison weapons, since crappy dot seems counter to her role, and replacing it with throwing blades. Also, perhaps move deathblow closer to the start of the tree so it isn't so point heavy to take it.
And evasion is 2op, I'm sure the telemetry data will show how everyone takes it ASAP, pls nerf.
TL;DR buff assassin pls because I love assassin and I am a special snowflake.
