Dungeon Defenders Level 1-70 less than 2 hours

Ramparts [Hard] (don't do insane, not worth it. Takes longer.)
Requirements:
Already unlocked Ramparts
Tower Squire (at least level 40 with semi decent gear for towers)
Your harpoons must do 1500 damage at least. (example)
Specific placement.
(can place extra towers for insurance, I show minimalistic setup only)

10 Minutes per map, that includes setup+waves.
Don't get hit, and don't let your core get hit.
(Sometimes random enemies will squeeze through)
Don't waste time leveling up between waves, just spam G until you see your character move their arm.

1st run you will get to 23 or 24. Every run after that you'll get less and less levels until 60 you will continue to get 2 to 3 levels every run until 70.
(so long as you and your core doesn't get hit)
