Im wondering is there any expert here on engineer tinkers, feels confusing.
First, can tinkers be considered “serious” gear, Breath of Neltharion one at least? They malfunction on specced engineers not to mention on non-engineers, they also have quite a cd, tinker gear is missing one secondary stat.
What are the differences between Breath of Neltharion rank 1 , 2 and 3? Tooltip says they all do same damage.
Alas, they’re not usually optimal except for the battle res one for M+. Breath of Neltharion has been good burst to have as a healer for big AoE pulls, though.
Very rarely, and never catastrophically. Its basically just costing a global when it happens.
This is actually a good thing. It has only one secondary stat, but all the stat budget goes into it. So you can think of it as doubling up one stat at the cost of the other. It makes stacking your best secondary even easier.
The tooltip is full of lies and has been since launch, im afraid. It scales.
This is great info, I didnt notice this. Does this mean it is actually BiS for everyone, with added “might-malfunction” flamethrower as bonus? Why arent more popular then?
Catastrophically means failing and going back on CD for 10 min?
I used one at the start of the expac and remember there are different tiers of failure.
I assume catastrophic is death or close to death, something like the boots throwing you in the air.
And iirc they all went on a 10 min cd.
supposedly if the engineer who makes the tinker makes it with a certain added part they don’t malfunction as much or rarely ever… there’s an item Engineers can learn from specializing in one of their trees that makes tinkers they craft and use tend to work as intended rather than malfunction and ironically they get the recipe from the tinker malfunctioning on them. I’ve got an engineer thus how I know
So engineer with talent in non-catastrophic failure should just use less chance to malfunction https://www.wowhead.com/item=198253/calibrated-safety-switch
and non-engineer should use https://www.wowhead.com/item=198259/critical-failure-prevention-unit
So, what is this doing? https://www.wowhead.com/item=198621/spring-loaded-capacitor-casing
You can still malfunction as an engineer.
You can’t catastrophicly malfunction specced into the profession point.
The reagent spring thing sometimes stops it from malfunctioning.
If I understood you right, tinker crafter decides how he makes tinker and puts it on AH, so you cant know whether it is crafted with safety component or not.
On second thought, safety components are reagent when gear crafting, not tinker itself.
If you’re specced into it, correct. You should use one of the other ones. If you aren’t specced into it, you really should, because the catastrophic failures are really bad - the Arclight Vital Corrector Catastrophic Failure straight up kills you.
Which I learned the hard way. 
Once it can’t catastrophically backfire, the battery dislodging or the less chance of backfiring is fine, either or.
The way the battery dislodging works is it puts a physical battery on the ground - if you click it, you have another chance to use the tinker. So if you have good spatial awareness, it’s essentially SOME of the time you get a negative backfire, you’ll get a chance to try again if you pick up the battery.
I personally think 15% less chance for backfire in general is better though.
I think, this is what calibrated switch is doing.
But what would dislodging battery mean from spring thingy? maybe longer CD?
This is great info, thanks.
Safety switch reduces the chance to malfunction.
The springs have a chance to stop a malfunction when it occurs.
Same result different ways of stopping it.
