Name Change: Quest reward / lower price / Nickname in expedition feature

I used a complex name that is very hard to type out accurately when we have to switch parties in boss runs. I am sure many feels the same. I was unaware of the need for this in end game play. wouldn't this be potential p2w?

I would suggest, make a quest that reward name change or lower the actual cost of name change?
Some of us in poorer currency country can't afford 20 euros, that's like 15 full meal in the country im from.

Or add a feature so we can allocate nicknames to ourselves and only applicable in boss runs?
