I'm purely a monster fighter, no pvp, so my opinions are purely based on pvm.
I wouldn't be opposed to some sort of damage buff, but it's ridiculous to have such lopsided shields in a shielding class, and that most urgently needs updating. Now that they've implemented tackle, dodge and pushback stats, I think earth and fire armors should give tackle, dodge and/or pushback protection, improving Fecas' value in team play. Adding these effects to our spells would give us a unique skill, something that will encourage people to bring us along in dungeons. Cras have range, Enis have healing, Xelors have AP steal, but right now Fecas aren't much better at defense than Enis with preventing word.
Also, I think character level should affect the amount armors reduce in addition to stats. When you're fighting monsters that do 400+ damage a turn, reducing that by 60 isn't enough. When you're fighting monsters that do 60 damage a turn, it's overpowered. This change would also reduce our dependence on diamonds to max out our spells, one of the main complaints in the first post.
And thanks, Muniamx, for including us in this summary. Let me know if you need any help with translations.
