Xenon Preperations

Pretty much this.

Also, am I the only one who thinks it to be silly to fund a Xenon to the teeth, knowing full well that they'll be heavily nerfed in the future?

If you research more and do some math you would understand that this was heavily needed. A level 200 xenon with no items and 200 w.att compared to a night lord (I know they're pomegranate but this was the example I used) with the same you would end up with 3x the range after adding boss dmg/total dmg into the picture, your skills would also deal more dmg and you would have a lot more useful things to bring like binding. The nerf knocks them down to around 2.2x the range of the current night lords, meaning they did not get heavily nerfed to garbage tier (phantom) but still nerfed to a more suitable spot for your skill set.

You will still however have a huge advantage in terms of hyper luk/dex/str & tyrant/nova gear, so even if you fund this char heavily you wont be totally useless.
