Paladin tanking help

[Susano]

I'm relatively new to the server, just started a few weeks ago and rolled up a Paladin. Gotten to lvl 14 and have been tanking the whole way but struggling to keep mobs on me. I use Flash of Light, but many times the mobs just turn to my other party members. Done a bit of research and I've seen some say it works like root in that it's proximity based agro, however, I've had melee in the group and even if I'm on top of the mob I still have them turning from me to whack on others.

Am I doing something wrong? Is it just a case of people having gear that does so much damage I can't hold agro off them? Feels bad when I'm trying to tank and I can't keep mobs off my group mates. Any suggestions from people who play Paladins here on 1999?

Thanks, and if you group with a low level paladin named Aryan, just know I'm trying :P
