Whats funny is that Blizzard seems to be sticking to their guns in passing the hot potato over to the ISPs, in spite of evidence that points toward the bug being unrelated to the user's ISP:
1. Reports of the issue skyrocketed at the start of season 4, which implies that it was brought on by a change in the game.
2. Large numbers of players in all regions across multiple ISPs have reported encountering these latency spikes, meaning its extremely unlikely that an ISP is to blame, or can do anything to resolve the issue.
3. The issue is most commonly reported as a spike in latency, accompanied by strange behavior in the game such as enemies standing still while player characters are still able to move (but not attack). These symptoms reek of either a server issue, or incidental packet loss happening at one of the "hops" between the user and blizzard. While the later is possible, its extremely unlikely that multiple ISPs across the globe are coincidentally experiencing the same packet loss issue in the same time frame. It MUST be somehow related to the game.
4. Blizzard support staff have been acting very fishy about this issue. They have been giving players obvious cop-out suggestions like "switch to a wired connection", or "flush your DNS". Not only have these suggestions been unsuccessful at resolving the problem, they also insult the intelligence of the player reporting the issue. First off, these kinds of tests are the kind of thing you try before you get tech support involved. Secondly, it doesn't explain why the issue wasn't happening (or was at least far less prevalent) before 2.3.
TLDR: Blizzard probably broke something and is either unaware or unwilling to accept fault.
If you want this problem to be resolved i suggest that anyone and everyone who encounters latency spikes should post about it on the support forum. They can't brush it off forever.

Blizzard has barely even begun to address this issue. They're just now acknowledging that it affects more than just Shaw ISP customers in Canada.
