Just incase your still looking for some answers.. this is a really great guide I've been going off.
su/te isent all that great.. but if your going for more of a support summoner it's okay. Basically what's happening is your grabbing the support aspect of Tech as much as you can to buff others and your pets as much as you can. But in gist. Your overall support capabilities are going down without Techer being your main. And without a high damage multiplier class your pets hit a lot lower then the norm for summoners.
So it's kinda like gimping yourself in two different ways. Less damage less support. But that dosent mean it's totally useless. You can still offer decent team support while also providing easy damage from pets. It may not be super high or ridiculous numbers. Pretty sure you can get an easy Marron rotational build going and have a Techer weapon in the very last slot if you really want. Otherwise you can still place the techs on the sub pallets and or have certain Marrons with certain techs or flat out have a Popple with very expeditious make it into a PP battery basically from autos while casting Zanverse and Magiverse for your allies.
Not the best but you can make it work. If you really want it too. However just remember there are better options out there if your maining Su ️
