Heh I used to play champ but was never really good at it. As for your questions.
1. Yes champ usually just asura in woe. They Runwatch and body relocate around to find hidden enemies too. Pneuma guild mates and fo if someone is in safety wall.
2. Et mid is good but awe/ewe would be enough.
3. I don't donate so I don't know the time about amazon.
4. Champ can use any other mouth piece too but as far as I know. In pvp def is essential to reduce damage during champ duel, so pcb is champs 1st choice.
Like I said at the top. I suck at champ but this is what I think to your questions. Hope it helps
