A few years ago there use to be an achievement for achieving low land complete and reseting your account - there was permanent equipment if you refer to wulfs equipment guide. This was later replaced by a badge as the devs stated this was to easy, they were correct my alt was achieving the goal in less than a few hours , however I would like to see the reintroduction of the ability to earn the equipment in some form as it's percentage bonus with the release of new lands and buildings will start to become more significant. It could be a reward for those that reset after unlocking highlands 5 times - looking at this account it's taken about 30 days but there were telescopes involved from the recent promo or could be for actually unlocking all the abyss lands. Currently only a handful have unlocked all the abyss and rather than encouraging resetting it encourages growth however the people that reset may require some compensation maybe a few lands unlocked in the abyss or xstals.
Support. New players to the game had no opportunity to achieve the resets and older players had no idea it would be taken away. So there should be some type of difficult, but achieveable mission/objective to allow players to get these items and the percentage bonus attached.
Promo equipment is a little different but could be made available by purchase as it seems they have made some war equip purchasable by mith. The difference between this equipment is it is permanent and doesn't take up an equipment slot so is really giving an unfair advantage over those who can not get it while eb and event equipment is always being superseded
