Seeing problems for old servers at ARR release?

[Obsy]

and to your seconds point.. well it did not hurt me either in FF11, when i joined the game after two years in the EU launch of FF11. just maybe the total opposite.
i was more like "woah i wanna become a fire man.. no ... a pirate.. ah damn.. i mean a fabulous Dragoon!" when i saw a lv 60+ Dragoon in full artifact armor and his beautiful wyvern.

i think it can be good for mixing up old and new players... to each his own.

This can and will still occur, as new players also have the option to join established servers. The purpose of the brand new servers is to play in a world where everyone and everything is starting from scratch.

but well i can easily imagine that there are many players out of there who are afraid of established economies. because they want to be the first one on the rank list.

I seriously doubt "being the first on the rank list" is the intention here. The point is preventing a fledgling economy from hitting the ground at ludicrously inflated rates to the point of prohibiting trade by allowing it to ramp up gradually on a more "natural" scale.

ETA:

the gils are going to be already cut down in ARR for old players.

It appears that you're still missing the point of redenomination. Gil (no 's' even when plural) is not being literally cut down. There is no loss of money happening. You're being given a dollar bill in exchange for the ten dimes you had previously. We've gone over this before. I don't know how else to explain it.
