Im pretty sure the upgrade mats will be from the tokens and will likely be 1:1 for either Right or left side with weapon being the exception. New weapons from the ex battle will prob be 205 and the relic being 210 after you've completed the quest. We are reaching the last half of the exclusivity window for 210 ilvl as raid gear, Typically on the last half the progress towards these items is increased substantially in the interest of gearing people for 3.2 This is the "catch up" patch.
Personally as a savage raider I have no issue with this. I prefer people to be on equal ilvl as it allows the good players to shine on skill alone while the mediocre players who's abilities were being proportionally inflated by rng drops to be back to where they belong.
