Some Monster Life's Inquiries

I switch my main every now and then (My current main is Wind Archer, not sure if I will switch again when RED and Zero come) so the bonus stat from monsters is already out of question for me.

Is it possible for one to own every Pipsqueak Monsters if the number of monsters slots is not a problem? Also, I would like to know why you did not include Pipsqueak Zakum and Horntail in your list? I can understand one for not having Pipsqueak Orchid, Mercedes and Phantom because their assembly formula requires their respective SS-ranked monster which costs a whooping 20k warus for each combination and the "success" rate is horrendously low.

I think I will need to reconsider again whether to get my Pipsqueak Mercedes or not

I'm a Paladin.

My Blast critical hits 100% of the time so Horntail is useless for me until Red when I actually need to use Charged Blow for that specialized skill and Blast buff.
As for Zakum.... chance to block attacks? When you take Guard, Guard, Guard, Guard, Guard, Guard, Guard, Guard, Guard, Guard, Guard, Guard, 1, Miss, Guard, Guard, etc. the chance at block is also useless.
