Element and Socket systems has been modified.
You will certainly have to check this note (major note, about Arcadia update) to see every detail, about how they work now.
Also, there's only one free Scroll given from a Quest of Gato, to reset your Elemental Points.
The only known change on a Set bonus that happened, to me, is this one:
Removed the "Attack Range" stat from Earth Master's Secmathian Set (3 parts) and replaced it by a different one (all grades: normal, rare, hero). We found out that this ability is bugged when used on sets. If you have any problems with this ability on other items please let us know.
If you've been off for literally a year, here's a list of changes I consider as major, copied from the notes, starting from April 6th 2016:
The "Flinch" effect will be removed from chain combo attacks and the chain combo modification skills (Diffuse Cannon, Double Shot, Smart Shot…) in PvP. This change does not apply to the PvE gameplay.
Added the Happy Jobchange! Quest for the 3rd Jobchange where you can obtain the Jobchange Box from Dustin at Village of Ash Mist.
_Galaxia Skill Socket Cards are now usable from Level 20~99. Card upgrading stays untouched at NPC Crete for the time being
_All F6 Rings are now socketable (also the lower level ones)
Other changes includes adjustements of Quests, adjusments of item restrictions (Market, Charge Mail, place of usage...), new Costumes, Achievement releases/fixes... (Maybe more, but I don't feel the need to mention.)
That's it from me; if you've got the nerves and need more to know, you might want to go through 5 or 6 pages of information in this section '-'
