Macros sometimes not working

I have a couple macros that are working most of the time, but there are times when I can’t press them for 5 seconds or more, then suddenly they start working again. The ones I noticed it on were my blizzard and meteor macros.
#showtooltip counterspell
/cast blizzard

and

/cast Blood Fury(Racial)
/use Dread Gladiator’s Badge
/cast Meteor

If it makes any difference, I seemingly only experience this issue in arena. I can stand still for seconds at a time spamming the button and nothing happens, it’s extremely annoying and completely ruins a lot of my arena games. If anyone knows what the problem is or how to fix it, that would be great, otherwise I might just have to stop macroing these abilities.

Probably the trinket. Try moving it down a line.

It’s also possible you’ve got an addon tainting things. I’d enable Lua errors and see if something’s being triggered in arenas.
