I don't know how godly naked you are, but i would suggest you go for BM equips which every player who hit 65 should get 1st before entering anything, even if u want to do Sauro 1K,
1. You must get at least BM Weapon(Eternal) and Accessories(At least the gold versions which u can upgrade later), forget about the armor. Its better you still hit the mobs/bosses than the attacks got dodges/blocked/resisted by them. This can be done the 1st week-2nd week you get lvl 63-65. If you at least dont have this, you should not even applying to any instances, not even Sauro 1K
2. Depends on your class, your BM equip buying path can differ, also you should do AC daily and shugo everyday, to secure that even if you fail to get a 65 mythic in 1st 20 days, you can still buy AC Weapon from your own farms. a +5 AC Weapon = a lvl 65 Mythic Random stats +10 Weapon.
3. A low geared DPS cant be brought to Sauro 2K, IO/RST, DR/Modor, IS/Katalamize(if there is already 1/2 low gear players in that alliance).
Getting yourself a AC Weapon and BM gears, will make you already a (almost) endgame player if you socket them good manastone. You dont need a +15 gears blablabla to call yourself a OP DPS trust me.
If you still need more suggestion or maybe go together some places, pm me in-game.
