General Game Help: Dread Knight, Ancients, and HS Runs vs. Deep Runs

I've been playing clickerheroes for 42 days according to the game statistics. I guess I'll post what stats I have, then just put my questions after that? (P.S. first post ever. Made an account for the first time so I could post) Gx3 Treebeast Gx5 Ivan Gx3 Brittany Gx5 The Masked Samurai Gx5 The Great Forest Seer Gx1 Dread Knight (Ran out of HS when I was regilding, last gild happened to be dread knight) Lv. 16 Libertas Lv. 14 Mammon Lv. 6 Mimzee Lv. 120 Morgulis Lv. 11 Siyalatas

Morgulis is the way I control myself when it comes to saving up HS. I got him early, not realizing it wasn't the best one. Now, I use him as my bank for DPS.

To my questions! Starting with run durations... How much more valuable are quick runs vs. deep? I understand quick runs for like 10-20 HS are ideal, but I get more satisfaction out of the game by doing longer runs. I get it will slow my progress, but I like feeling more accomplished than just getting to lvl 150 or something then restarting. Is it an inexcusable mistake to do deep runs because I find them slightly more fun? How much further progress would I be making by doing quick runs? Dread Knight: Is he worth getting? In my most recent run, I am at lvl 270. I have all the gilded heroes at lvls 1100-1250ish. I just bought dread knight for the 10kU because that is now around the price of 25 levels on the other hereos. He's only worth 27.5% of my DPS for that price. Is he something to save for and put a point (or more) in, or is it more effective to lvl up the early gilded heroes? Finally, ancients. I've got some goods ones; I've got some less good ones. Which currently owned one(s) should I be leveling? Which one should I buy next? Berserker, chronos, thusia, and argaiv are my options without rerolling, argaiv being the only one I'm slightly interested in. However, argaiv won't be as powerful until I have more gilds. Is it a good idea to reroll? Should I just buy argaiv? Which ancients should I level up?

All right. This was more than likely an excessively long post. I hope some of you learned clickerheroes veterans were able to get through this and help me.
