as a main support i think he is not a whorty pick over most of all other guardian (and maybe some warrior). i think he really need some help. why is 1 is supposed to be a guardian ability ? he just spawn a little turtle. not even a slow on it. you cant engage with your 3 and thats give his 3 no synergy with his kit (you must be in team fight to make your 2 usefull. but you cant engage with you 3 cause you will push enemy away from your team. if you have blink thats fine ofc) his ult is meh. is great for keeping ppl alive. (but he should be an aggressive support with that 2, so maybe pulling ppl toward him istead of pushing them back would help him. it would also makes sense. if you spin a spoon in a glass of water you will create a whirlpool, and whirlpool usually pool things toward the center.)

His passive and his 2 are good. no need to change them. still probably better than xing tian or fafnir atm as support.... but just maybe.... not really sure about it cause i play xing tian very well so i still do good with him (and fafnir too). absolutely not a worthy pick sadly.

kuzenbo seems underwhelming like many pro players already said (i know that someone said the opposite... but i actually think he needs some help. well ofc, still less help that Hades or Zhong needs :P)
