This is what I do when making macros. Nevertheless, it’s far from easy to translate that into a macro due to it being dichotomous from actual manual gameplay.
You’re right though: it’s usually a case of tweaking existing ones.
If it’s a simple issue like adding an essence line then fair enough, but the subtleties of spell placement within a Priority or sequential macro can be difficult. That and due to gear and a host of toon dependant factors = some macros don’t work well for certain players and some work even better than they’re meant to!
Its just a fact that someone with ilvl 443 is doing 31 k and myself with 454 now is doing
30 k, thats wrong, and im trying to find out what it is.
Hell even the pala healer with lower gear on seth 10 was doing more dps then me.
Tried setting spellque but gives me a :
so i guess this does nothing?
Did set the " SET SpellQueueWindow " in config-cache.wtf, am not getting an error ingame but still dont know if it does something.
the wowpedia is above, getting an error seems to me the variable has been removed or made locked.
edited indeed, the tone was not right, but it gets me frustrated. Again a char i like to play and getting geared
finding out it does less then way lower geared people in whatever enviroment. I play all chars and try to lazymacro on all, just cba pressing buttons anymore after all those years.
60 default is gonna basicly almsot be the same as 400 i would recommend 100+ ur current latency and abit more for me ingame MS is 25 meaning i would have it at 125 but instead i have it around 130 ish
Using droptimizer on raidbot now to find upgrades and seems that one of trinkets is pure shizzle, still that upgrade wont account for lets say like 5 k minimum dps loss.
Was flasked and maximum food buffed ( 360agi- 93 vers ) when doing test.
You have an on use trinket being activated and its canceling your eye beam early or you are using a heart essence that is doing the same thing; you can turn your trinket use off in GSE by on the right hand side of the panel while viewing pacmans macro. Then add /use [nochanneling] 13 or 14 to the sequence to still have your trinket used for you
There is a hard use setting which on my UI makes the marker box yellow, then there seems to be a “soft” use setting which will trigger its use less it’s marker box is grey and when it is off the marker box is black, to me anyway thats how it looks using evlui glad I helped
im about done with updates to dh tanking macro i will start working on the changes to havoc macro tmw its not much i was gonna change just a few things to make it work more efficiently its just me doing trial and error about 40times xD
