Is reload cancelling an exploit?

One advanced tip I can give for vanguard players is, you can cancel
out of a reload animation to melee an enemy and you will still reload as
long as you've completed 60% of the reload animation. It's tricky to
master, definitely for more twitchy players, but it really helps with
the claymore.
The reload trick is by design. It isn't a glitch. I know because I put it in on purpose!

I tuned the reload trick for consoles, if it is significantly easier to do on PC that was not intentional (but I wouldn't patch that away). What makes it significantly easier on PC so I can try to replicate it and tune them separately for ME3?

The reload trick is an example of canceling animations. This is a pretty
common technique though it is primarily used in fighting games....

If you don't like the reload trick, by all means don't use it! It is supposed to reward coordination and timing.

99% of players will have no interest in the reload trick, it's a
very advanced feature, that is only useful with certain playstyles and
weapons. It doesn't make sense to present that information to all users
in documentation. Documentation is generally for core gameplay concepts
that you need to understand to play the game.

Also reload trick is kind of a dumb name we should really call it reload canceling.
