I respectfully disagree. This is only a problem if you are teamed. You can always heal / fight / whatever out of team. If you miss the ability to join Team Chat, set up a new channel (it's easy to do). Any master should be eager to help others to level up, whether it's your guildies or whoever.
That sounds to me like you never, ever, ever choose your heal targets with the team list when the screen gets cluttered, monitor the condition of their teammates at >20m range, or use the map to locate people you are playing with. There are MANY more benefits to teaming than simply sharing a chat.

Do not assume that you speak for all just because you are the loudest voice; there are many who disagree that simply have no desire to waste words on you.
