Yes, having multiple tamers is definitely an addiction. I currently have 23 of them, spread out over ten shards (Atlantic, Baja, Great Lakes, Lake Austin, Legends, Napa, Oceania, Origin, Pacific, and Sonoma):
<ul>[*]One mage tamer with 120 real taming; one mage tamer with 108 real taming; another mage tamer with hiding that's at 100 real taming.
[*]Thirteen peace tamers. One has just over 110 real taming; three are at 100 real taming; four are in the low 90s, and the rest are in the high 80s.
[*]Seven tracker tamers I use or plan to use for factions (skills are taming, lore, vet, magery, detect hidden, tracking, hiding, stealing). A couple are completely finished and have 90 real taming; the rest are still in development with lower amounts of real taming. [/list]
All the tamers have (or will have) their real lore skill worked up between 110 and 120. I hope to get all of the mage tamers and peace tamers to 120 real taming someday. The tracker tamers will probably never go any higher than 90 or 95 real taming. All except the tamer with 120 real taming are still wearing taming jewelry. One of my goals is to get as many of them as I can out of wearing taming jewelry because I like knowing that they can command the pets after being freshly rezzed and still in a death robe and the pets aren't losing loyalty or ignoring commands.
I've been trying to get more organized with keeping track of all the tamers' pets. At last count, all of them combined currently own 131 "high-end" pets (1 bake kitsune, 19 cu sidhe, 12 dragons, 3 fire steeds, 6 frenzied ostards, 5 greater dragons, 17 greater hiryus, 29 nightmares, 17 rune beetles, 5 unicorns, and 17 white wyrms). I wish I could say all the pets are fully trained, but they're not. But that's okay, because I do enjoy training them.
