ForteXorcist is the best dot timer in my opinion. It will give you a few things other dottimers won't: 1. Separates target's dots and focus target's dots into two sections. 2. Separates important cooldowns (like lifetap glyph, haunt cooldown, trinkets) into a third section. 3. Gives you "ghost bars" which precede the timing bar's edge by the precise amount it takes to cast that spell. For example, UA takes about 1.5 seconds to cast. As soon as UA's ghost bar passes the left side of the dot timing bar, you know you can start casting UA without fear of clipping it before the last tick. 4. Xorcist also gives you a summon list of members who are far away and need to be summoned, when out of combat. No more "Press 1 for summonz!" 5. Xorcist also has a separate cooldown timer gadget thing, but I don't use it. Some people love it, but I don't need it. Drain Soul Timer is useful for one thing: It has an option to play a noise whenever Drain Soul ticks. Very useful for redotting during execution phase. Tell me when is a mod similar to Power Auras that pops up icons when something is active/inactive. Useful for reminding you when to lifetap, or when a trinket is ready for use, etc. Power Auras lets you set up conditions to display neato symbols on your screen to remind you of things. The two you can see in my screenshot are my BUFF thing at the top, and the green circle INSIDE my HuD life/mana display. This inner green circle represents (to me, since I set it up) that I'm in range of my demon portal and it's castable.
