Is focusing on -recharge worthwhile?
The -rech floor is -75%, so your 150% is severe overkill for +0 enemies, but just about enough to floor +4's. Of course, most of those procs will not be up most of the time; Distortion Field and Gravitic are the only ones you can reliably apply to a whole crowd.
Large amounts of -rech do make enemies do a lot less damage over time, but personally I still wouldn't trade away a DoT interface for it.
But what do you think about the overall concept? Good idea, bad idea? I'm not even sure I'll incarnate the character, and if I did, I would also most likely take a DoT interface. I just added Gravitic in there to make the most extreme example
I've been lvling up an Ice/Time troller and even though I'm only fighting +0 or +1 enemies, I'm noticing the impact of -recharge versus my other trollers. It's not a huge mitigation, but if you can get it use it. I'd not build quite so heavily for it, since there is a ceiling and you'll hit it pretty readily. I plan on using the DWD in Time's Juncture coupled with Artic Air's -recharge to further mitigate melee attacks. I don't think I'd go as crazy with the procs as you are suggesting, but maybe one in distortion field. I'm kind of thinking of picking up another interface besides reactive since everyone and their mother seems to have it and if you team you'll be hitting the 5x stacking cap on it real quick. Solo, it's hard to not pick it though.

I wouldn't. The prob is your -recharge doesn't prevent dat alpha, and taht prob the thing you nee to worry about the most
I made and ice/storm corr focused on -rech, it didn't feel effective. I deleted by 25, so maybe I just didn't stick with it long enough. I'm pretty sure I was getting over -100% rech by then though
I have an Ice3 Dominator, which is -Recharge to begin with, who has a -recharge proc in every attack (Basilisk's Gaze, Pacing of the Turtle). When I get around to it, there will be a Gravitic Interface as well. This is all on top of Arctic Air, Shiver and Chilling Embrace. I've fought arch-villains with it; didn't have enough DPS to beat them, but they didn't have enough DPS to beat me either, if you catch my drift.
If there's a lesson here, though, it's that while -Recharge builds can be very effective, it's one of those things where you have to know what you're doing or you're not going to see a lot of success. Per-Enhancement, you'll likely see greater benefits slotting for other things like Defense or, as is the case with Time Manipulation, -Regeneration (besides, Diamagnetic Interface is quite handy on Masterminds).
If -Recharge is what you want, then go for it and you won't be disappointed. If "utmost effectiveness" is what you want, even not from a min/maxing perspective, you may want to reconsider how you allocate your Enhancement slots.
I'm leveling up a Ninja/Time mastermind, and I'm thinking of doing a heavy focus on -recharge. I could have
1. Time Crawl, -60%
2a. Distortion Field, -50%...
2b. ...also slotted with the Pacing of the Turtle (-20%) and Basilisk's Gaze (-25%) procs, 20% chance each
3. Pacing of the Turtle (-20%) and Dark Watcher's Despair (-25%) procs slotted into Time's Juncture, again 20% chance each
4. Gravitic interface (-10%), 75% chance
I'm wondering if it's worth it to do this in general (like maybe with an Ice or Psychic build), and obviously specifically for this character. If it is worth it, have I overslotted? Is there a -recharge cap? On a single target, that would be up to -210% recharge if everything activates, and up to -150% for everything around it considering the AoE capabilities of the build
Also do AVs resist recharge debuffs?
