Very much true for the most.
Your comment on the exp buffs is something I agree strongly with too. The 'benefits' it grants is limited (and of course for heaps of other factors), but does not always seem to be worth the purchase.
Nonetheless, luck buffs ("event" based) could be not so much for "rare" items, but for those wanting to build up the +5's and beyond. They could also change up the loot pool by switching about certain items, hehe. Perhaps an 'extremely rare' drop could include Bot type changes, combination tickets (I forget the proper name), and maybe a snowball every now and then. It would for sure help the market a long a bit. If there's a consistent income (or possibility of gaining items), then prices become moderated by the market on it's own (through natural supply-and-demand cycles). Also, it can help keep the community motivated and eager to clear the sectors in hopes of maybe a one-day membership.
[ I think as well that the reference of "event items" as rare's is a little misleading (I know this has become colloquial terminology in BC), but an introduction to a genuine "rare" item tier would be nice too. ]
Also, another really off-the wall idea; it would be nice if we could get equivalent armours to RT1/RT2. Having every bot look the same does get a little boring haha. Even if it meant making RT1/RT2 with same stats, but with different skin colours I think would just add a little bit of variety in game
There would not be a huge amount of coding to do that, and re-skins I think is something BC does quite well - the Raid Armours were very well done in general. Alternatively, making other sources for ascertaining armours of equal status would be pretty neat. Because currently, you either need to find a good Raid runner, or a decent Raid team to get RT armours as "end game" hehe.
Coupon idea also sounds pretty good haha.
(I also think staff armour should be rebalanced to equate to either RT1 or RT2 standards. Staff armour should be usable like max-tier armour. That way, it grants incentive for staff to actually wear it in game. And sure, the staff skins are a little wonky, especially on the patch, but I personally think it should be a thing of pride and "representing" Zylon
. I know however a lot of staff only wear the flags, and not the armour in-game because of the stat discrepancy.) <--
Just a very personal thought.
