MMOexp Lost Ark: A few inquiries to LA

Me and my companions need to begin LA this evening. I couldnt track down the responses on these inquiries:

- Whenever me and my two companions are in a gathering on a similar channel. I kill a beast, do we as a whole get 33% of its exp, or do I get something else for killing?

- Do we share exp despite the fact that we are on various guides?

- Hw numerous players can join a gathering?

- My companions need to play military craftsman and shadow tracker Im stuck among paladin and summoner, which one do you suggest?
