Concept Skill: Holy Heart (elite)

Holy Heart (elite)
5 energy
1 second recharge time
60 second recharge time
Enchantment Spell. For 10...48 seconds, you're maximum energy is doubled but spells cost 3 more energy. When this enchantment ends, you gain 1...15 energy. (Divine Favor).

At first glance this may look like a terrible skill. But if you think about it proportionally, this skill can actually be useful.
Your energy is doubled, spells cost 3 more energy. You might think you're spending more energy, but in the long run, you'll be saving energy.
Let me lay it down.
5 energy spells:
5 energy base without this enchantment
5+3=8 for double
But divide that in half and proportionally you spend 4 energy, you saved 1.

10 energy spells:
10 energy base without this enchantment
10+3=13 for double
Divide that in half and round up, you spend 7 energy, you saved 3.

15 energy spells
15 energy base without this enchantment
15+3=18 for double
Divine that in half, you spend 9 energy, you saved 6 energy.

Then there are very few 25 energy spells to worry about.
And then you gain 15 energy to "make up" for the lost energy.

This'll probably not work for Monks trying to pull off elementalist spells that have exhaustion. Hehe, this thing ends, you're screwed with like 5 energy in your bar because of exhaustion taking up the rest.
I do understand that you'd probably need a blood necro to use BiP or BR on you for I understand that 4 pips of energy regen can be a little bit slow for the extra cost.

hum well this is a good skill but giving monks max nrg that rivals an eles does not seem fair lol but idk this is not the big of a game breaker but im not /signing or /notsigning lol

Is the extra energy cost not a good penalty? Or should it be raised to 4 energy?

I think simply having more energy is a penalty on its own. It would make it that much harder to hide your energy when a mesmer starts beating you down with e-denial.

I would personally never use it because of its long recharge. Sure the duration is long, but what if it gets stripped? then you are screwed... especially if this is your only e-management skill and the "fecal matter just hit the rotary oscillator" for your team.

I can't even think of a way to fix this idea so it would work >_<

Would the Recharge time to 20-30 seconds be better?

Remember that you energy can go BELOW Zero. When this skill ended, you would still have lost the energy that you are claiming to be "cut in half". Exhaustion works with the same principal. If you were to use this skill and spam exhaustion spells, when it ended you would be stuck with a temporary "negative" exhaustion.

what about making it non elite ? maybe you could find some synergy

Would a shorter recharge time fix that?
