How many hours did it take for you guys to complete level 35 kharacter mastery and level 15 Kameo mastery for one-one each?
I am 32hours in mostly played with Sub-Zero and Mileena and got both to level 17 each. Kameos Frost and Sub-Zero are level 7 each. This is looking too slow in my opinion. I've completed story mode and Invasions mazes.
Go to Fengjian Village's level 1 endurance match 'Triple Threat', put all your points into attack, use the 15% XP booster relic on your talisman (there's no armor on these opponents) and simply get flawless victories and always use a finisher on it (if you equip an armor talisman with 8 charges, I've upped mine to 14, it's guaranteed as you're invincible - in fact I think mine's bugged, it never goes lower than saying I've used two charges). The fight takes like than 10 seconds and you'll be getting huge amounts of XP every time, the early levels will level up just from a single fight, by the teens it'll usually take around 6-10 fights, as each of the 3 characters counts as an individual victory. You'll get even more XP if you do it on a higher ranking mesa, however those tend to be plagued with secret fights, so this is quicker over all.
I'm XP level 100 already, and have leveled Mileena up to level 24, Sindel to 20, Ashrah to 27, Reptile to 18, Sub Zero to 10 and Smoke to 15. Kameos I've got Sareena to 15, Sonya to 14, Shujinko to 13. I've also cleared out the shrine, completed the story, 100% completed invasions and bought everything from the season store, played for 57 hours (but that includes a few times I went out shopping having left the game on the kustomisation screen).
I've just leveled Smoke up from 15 to 16 in the time it took to write this post, going to take him to 20 this lunchtime to get the sweet loot. Sure it's rather boring, but if you just want to get all the level gear, it's the simplest and quickest way.
Haven't edited anything about my level in the above image, just redacted my son's user account name we play on for privacy reasons.
