why summoner only got 2 new pets not 3 no tank pet ?

so i reached lvl100 on my spectral master after comparing the new pet with the old i was really disappointed
Disappointed would be an understatement 2k more p attack is about all the difference
why didnt we get a Tank pet upgrade? i compared Night Shade to the New Soul Specter Night shade has 12k more health 2k more p def 3k more m deff and so on
why wouldn't ncsoft give summoner all 3 pets ?
doesnt make any sense how the summoner going to pvp with a pet thats lvl 99 when i will be 100+

Because the new pets are supposed to be PvP oriented, and they don't want to OP them with pets that do amazing damage and have laughably high Hit Points and Defenses. You can always use the old ones, if you want.
