Let's start with
Xbalanque:Well I love his passive change. no more needed early aggression or complaining about kill steals. A good change. After all this time the only thing that changed was his tier list ranking. Oh and my ability lvling sequence to the meta one using
Branching Bola for clear.Now
Vulcan:well I don't remember him playing so clunky as he looks, however I quickly managed to get over it. So he changed only a bit which isn't really noticable. His passive got a good change. however before he slowed so the effect stays mostly the same. One thing that is quite annaying is that his turret is pretty squishy, which is kinda a shame.
Next
Vamana:Only his moddel changed which I like. I love him just to make clutch escapes and easy wave clear. So build wise warrior's changed, however I still prefer
Hastened Katana(fatalis) on him over 
Frostbound Hammerlastly
Ullr:I'm actually crossing him off the list after one game. I still don't really like him with his switching. Do like the UI update to show your CDs in the other stance. after that he is quite straightforward. Maybe I will throw a game in somewhere however not quickly.
So just a small update
2-3 puts you in a bad spot early or you don't clear effectively.
In a teamfight mode like arena I will pick that order and not even bother with bolas before getting trans.
