So what happens is a lot is guilds scream we want healers (or we want x that is never tank) and then when those people wanna do difficult content, they cant. The boxed notraidgeared knight or the mage pet doesn't cut it. So every year we see "recruiting clerics" and eventually these guilds, usually led by over half tank leadership, fail.
So yeah. If you need clerics, is it gonna be worth it?
Yep, Yerm knows the pain. Every TLP guild wants Clerics for days, but most do little to help / accommodate them. Honestly on Selo we kinda lucked into our Cleric situation, I massively over-recruited Clerics, and we got lucky in that a core group of them stayed for almost 2 whole years. Most of them had some sort of static / support system in place to help them get stuff done.
If you don't have that it's an incredibly terrible class to main, you cannot effectively solo anything, and the way EQ works in later eras, if you box a tank alt for out of raid content--that alt is often worse than a Necro pet unless you've been able to acquire a significant set of raid quality gear. It's honestly kind of a shitty situation, and it's one reason I've always tried to have at least SOME avenue for people to get alt gear in any guild I've ran. If you don't allow alt gear, the classes that are High Raid Value but poor as an anchor out of raid, get put in a really bad position. A CLR is not even an ideal group healer, but are very necessary for raiding, so not only are you maining a healing class that can't anchor a box group very well, you're not even playing the healing class that is better at group content (SHM due to buffs / slows, dps etc.)
I've actually had this argument in most of my guilds too--someone will eventually see a CLR looting raid gear on their alt WAR or SHD, and make the comment "that alt is useless to the guild, we'll never use them for raid tanking, should we even allow alts like that?" If your answer is no--okay, then you need to obligate your raid tanks to group with the raid clerics X number of hours per week, because otherwise you're telling CLR to show up and heal, get loot that mostly doesn't power them up meaningfully, and have zero ability to function outside of a raid? Fuck that.
