Greetings,
We've been seeing feedback stating that the frontline jobs are the ones that are really receiving the benefit from weapons with item levels, and that elemental magic is suffering as many feel the spell damage is not increasing much for higher tier magic. Due to this, the trend is to repeatedly use lower tier magic, which is causing TP to be fed to enemies at a higher rate. The development team is aware of the situation and below is a comment from Akihiko Matsui who shares some insight into development ideas.
