Rayu, and what have me you think that its not what i was thinking about ?
think about it, DOTS aren't burst damage, heres why...
definition.
Burst = sudden impact.
Dot = Damage over time
the definition of both words are actually pretty much descriptive as to why dots cannot be burst damage. there is usually a 3 second delay before the dot actually kicks in for the first time, and thus isn't sudden. nor surprising as the guy who is looking at his screen will have time to react to it. even worst, it can be dispelled in that time span without it triggering ever. while a fireball or flame shock original burst cannot be prevented at all as they are sudden damages that just happens.
let me add this definition to help understand how i see burst and one shot moves.
Nuke = A spell that just does massive damage and threat. ex: Fireball
Nuking is the most basic form of damage from casters. burst damage to me is the basic form of damage melee uses. the only difference is in when does that damage starts being counted as burst damage.
rogues and warriors, even paladins, starts at the very moment their first damage was dealt which is pretty much instantly as they pushed the buttons. while mages and casters mostly have delays which can only be seen by their cast time. that delay gets them quite further away from the sudden burst because they need time to cast. and thus the effect of surprised necessary to make a successfull burst go down quite fast for them. the why its hard making surprise attacks from casters.
to me its quite clear. your Dots, even though i agree that warlocks have been the best classes in making people die suddently out of nowhere like 30 minutes after the original fight. it is simply impossible for them to one shot a guy with dots only. they can one shot a guy with their nuke. but not with their dots. its also why its impossible for them to have dots being bursty. unless you count the burst the moment they first hit and start calculating at that moment instead. but the opponent will actually be aware of your presence to begin with.
thats also why we are saying that burst damage is the time before your opponent can react to you.
as for the "one shot" remark...
you mean to tell me that all 3 dots, when they tick all together can actually get rid of your 5k life. i find it hard to believe all by itself considering i dont know any warlocks at 39 fully geared able to do a shadowbolt for that much. and its their most powerfull nuke.
