I've been pretty content playing solo PVE content with my Nightblade main, but recently I've gotten interested in tackling some group PVE stuff, trials etc, so I leveled a healer (Templar, Argonian). I'm almost CP400 now (from my main) and I'm still taking my healer through the main story and planning to go through Mages Guild and some Cyrodiil for skill points and skill lines I still need for this build, but while I do that I wanted to ask for some general advice for someone who hasn't done group content before? I vaguely remember doing City of Ash and Elden Hollow back before the One Tamriel update but I don't think that little bit of experience carries over after all the updates over the years \o/ I also still have to get good gear for my healer, any advice? The builds I can find online only really list high end gear that I don't think I can get just yet lol

I'd appreciate any tips, no hard feelings if I made mistakes or need to change something, I'm completely open to anything right now! I've never been a huge fan of multiplayer games but ESO is too much fun so I want to give it a try

EDIT: This is the build I'm following right now, if there's any that might be better, I'd love to know! I have the respec scrolls from leveling rewards so I can change up everything right now!
