Couple questions from a returning player

[Velerin]

Been playing on TLPs last few years and just came back to p99. Trying to remember what is and isn’t around on p99 and which are just not in green and will eventually be on later.
1. Stacking dots of same kind from multiple people
2. Seeing debuffs/buffs on mobs and/or group members, pets
3. Seeing mana of group members
4. Getting buff wear off messages for group members and pets

Thanks!
