I'm not sure what a rotation is, but you do have to put your builds together with consideration towards your energy pool and cost of skills. There are several ways to mitigate the energy consumption, of course--armor runes that increases max energy pool, skills that increase energy restoration (I know there is a spirit--most likely "zealous something" that will restore x energy every time it hits), and weapon mods--always "zealous x" that will restore 1 pt energy for each successful hit (also reduces by 1 pip your total energy regen).
IIRC, a lot of those spirits are very high energy costs, so you really need to be careful about choosing carefully. You often don't want more than 2 of them on a general rit build as the energy costs are too high. I tend to focus on the 5 energy cost spirits--and skills, for that matter--and limit the 10 energy skills. 15 energy skills; you probably want ones that have a long time of effect to outweigh the cost. There are also those "ash skills" that rits have, where you regen energy, health, whatever, as you hold it, and gain some sort of boost when it's dropped. On top of that, you have spells that have effects "while holding an item," meaning, the ash skills. For most successful builds, you want at least 4 skills that are tied to each other, and generally with the same attribute, so that you can max out one attribute, and have two more near the top.
I fooled around a bit last night, and discovered that all of my build templates are saved to hard drive...which means they are not available for my recent re-install on the newer desktop. Good thing I still have that hard drive, haha. I must have a few hundred build templates saved to that.
One thing that will make your life easier, OP, though will take some time to establish, is collecting all 3 Nec heroes asap--but this means getting to LA in Prophecies, a bit late in Vabbi for Nightfall, aaaand, I'm not quite sure where that 3rd female Nec is? probably EoTN? also--collecting the proper skills.
look up "Sabway hero build" on guild wars guru. it still seems to be rather effective, and is almost like autopilot through much of the game. And putting something like that together is a rather decent goal that will take some time, expose you to large, diverse areas of the whole series.
But if you don't have EoTN, it may not be worth your effort.
