Do I have enought End to run this build?

I have a 50 Kat/Reg and I currently have about 4.05 end/sec on it...I've been thinking about retooling it to get a bit more recharge and this is what I came up with although the end is lower: 3.57 end/sec. Will this new build be able to sustain a long fight with all the toggles going which drain at about 1.18 end/sec?

here is the build:

Oh and my attack chain is DA -GC - GD - GC - SD repeat...with an occasional LD if it's a big group.

I think you can answer that question. Add up the endurance costs of your attack chain, then divide by the total time it takes to do the attack chain. Mids' can be set up to show Arcanatime. If your endurace cost per second for attacks, added to the cost per second of toggles is greater than your recovery then you will lose endurance at the same rate as the difference.

When it comes to endurance, an ounce of savings is worth more than a pound of recovery.

Well, I am damn unsatisfied. Any tips on how I can increase the end but keep def and recharge pretty much where they are?

Here ya go. You lose about 1 second on Shadow Meld, and about 3 seconds on MoG, and a whole .1% defense, but it gets you up tp 4.09% recovery.

Just a question, are you including the alpha slot in this mix? Alpha Slot = Do anything you damn well please ability. Cardiac if you need the end.

Also, get the atlas medallion accolade. +10 endurance makes an enormous difference on your recovery since it's percent based, it's easy to pick up and I notice you do not have it (or portal jockey) activated on mids.

Those things will get you through anything if you're afraid of it not working in the meta.
Also, one of the bank missions gives +5 endurance for 3 days gameplay also, 72 hours gameplay is a LONG time.
