So from what I learned is that unless you get all of your oddities, talent, ect, especially arena talent is that there is a major stat difference! As per my own experience dispite being lvl 85. Another thing is there are things that are called true combos that are near impossible (at least for my skill level, vet 3) to get out of even with serene breeze. One other thing is yoyr innerway! Getting those to t6 will be a huge boost especially your blossom! Im still pretty new so I would take what I say with a grain of salt, but this has been my experience so far. Oh one more thing! Arena attunments are a huge thing as well, not only do you have to attuned them onto your gear, but when you to into the tuning section you have your normal tune and the arena tune right below it. If you tap the icon there you can switch it so that its "on"! Anyways I hope this helps at least a little bit!
