In the raid lobby, there should really be an option to communicate with the players who have joined the raid. Sometimes I’m sitting there thinking, oh no please don’t use that dinosaur. Rather than kicking that player out, I would prefer to give them advice on choosing a different dinosaur.
Even an option that says “We need a shield destroyer, a healer, a distractor, etc” would be extremely helpful.
Another option that would be beneficial is a emoticon that allows players to say during the raid “look at the boss’s next move”. Lot of players are quick to just select a high attack rather than playing strategically, so I think this would be a helpful learning curve for those new to raids. This would be especially beneficial since the boss’s move is displayed in advance and only the minion(s) moves are kept secret.
