While I'm sure all us "real" smns look down on the "abyburned noobs"....
I think this is going just a bit too far.
I know that I, myself, am guilty of this elitist mentality of looking down on the "abyburned" smns... When I catch someone about to do it... I tell them to stop... and offer help with leveling them more naturally... Partially so that I can help them be a better smn... but also so that there are less smns in the world with a skill level of 84 at 99... (and that's being generous)
But if the person who abyburns their smn up to 99 and then goes and takes the mind numbing time to raise their skill level artificially like how you mentioned... I say, let them do so.
A smn with the talent of not burning the job from 30-99 will always exceed the talents of the "abysseanoob".
But we shouldn't try and punish them more than what their own ineptitude will bring them.
And given how post-Adoulin content all seems to say "screw levels 1-98, abyburn your jobs now!".... I'm looking at you, GEO and RUN AF..... 1.....
I think it's even more wrong to punish people for embracing what it seems the game itself is promoting.
SMN is a weird job... it takes thinking entirely differently than all the other jobs. Even the other mage jobs!
But the thing is... the current paradigm of playstyle... just doesn't fit with smn.
SMN is the job that practically says "abyburn me if you want.... but you will be sorry."
And overall, I don't mind abyburning..... But we, as "old style" smns, should not punish the "noobs".... we should seek to guide them and deter them from making this mistake with the job.... or at least inform them that they will have months of nothing but skilling up. (I don't even think Liminus earring helps with smn skillups... it might for the actually summoning... but I don't know.)
