HRP system are pretty useless, no one does it, so we need some changes here.
for my opinion need some boost for rewards:
1) buff not for 3 days. 3 days, really? you need to spend ~2 days for got your level 400 only, you can't go for some bosses without level (ferea, nix, LA, AA, RI, Canyon, SOD, Vulcanus)
i think 7 days buff will be interesting. you get your HRP and 5 days you play with boost on level 400.
2) 10k RUUD it's don't interesting. you always can farm more just on Vulcanus. more RUUD will be abusive by alts. i think need to change reward from RUUD to x30 Jewel of Souls. you can't farm Souls if u wanna it, only some chance from MURoomy. but you need it for 3rd/4th wings, mastery set tier up, level up items from +6 to +15. Blesses you can get from WW, BC, Pandora pick. Jewel of chaos/Creation you can get from EvoMUUN scrolls, Harmony you can farm relic/maya hands, only Souls and Lifes you need to farm just from mobs. But Jewels of Life don't need much. So i think x30 Jewel of Souls for HRP will be not very abusive and normal reward.
3) 1 lottery coin for 10 bon and 500kk? it's just a OMEGALUL. change it to 3 tickets for 10 bon + 500kk, or just ticket for 500kk and maybe someone will do this.
OR you can create new item - HRP box, and when you get your HRP you got normal reward, like just now 10k RUUD/1 coin/Buff and this HRP box. From HRP box you can get some items with chance, like:
x50 jewel(40%), normal capsule(30%), some RUUD(20%), condor feather(5%), TOCA(3%), eTOCA(2%) - nothing special what you can't get just from gameplay.
Guild rewards are interesting, but requirements too high - nobody does it. maybe need to some decrease.
