Sounds good, right? Yes and no. There are a few weird quirks with periodic damage spells -- casting a DoT while under the effect of a buff like a trinket proc currently means that every tick of that DoT will be boosted by that trinket proc -- even if the actual buff for the trinket has worn off, an effect called "snapshotting." In addition to this, haste modifies DoT and Hot uptime. The more haste you have, the faster your DoTs will tick. In some cases, stacking enough haste meant that your spell would actually get an additional tick of damage or healing -- which led many players to look for that mysterious magic number of haste that would allow this effect to occur.
A lot of this is changing in Warlords.
