I like the mod but life regen is incredibly powerful. I'm a Warrior in Expert pre-hardmode and I already have 41 hp/second. I'm in the process of making a new character, a mage, so that I can feel a bit of danger again.
I feel like the Energy Shield mechanic is a solid option for players who don't want to pop potions, but making health regen so powerful feels devastating to it. Why would I play ES when I can just have 1500 life and 70+ regen/sec with superior levels of armor.
On the flip side, offensive options feel /very/ weak, with the exception of the crit damage cluster. 2% Melee damage vs 40 life is almost a no brainer. 1% melee damage vs 1 defense, 1% crit vs 1 defense..when you can just run every defensive point and reroll 2 accessories to crit to make up for the loss.
Lastly, The game's difficulty feels too low to warrant such powerful effects. Naked, I'm level 63 with almost 1,000 life, 40 energy shield, 40 hp/second and 10 armor. Those stats already nullify much of the challenge. Add armor in to it, and another 20-30 levels of stats and you've got a monster on your hands who can just AFK through any boss fight.
IMO: Tone down the defenses, Tone up the damages, Remove life regen or greatly reduce it in favor of ES or add content to challenge characters. Just my opinions!
All in all, great mod! I love the ideas and things I see here! Thank you very much for putting this out there for us!
