I can sympathise with you, OP. I had dial up internet until 2010. No other options were available and … I was addicted to World of Warcraft. XD
The struggle is real, my dude.
And I honestly think people are being a bit harsh with their attitude and wording here. No one has the right to tell you what you can’t do (well except Blizzard, in this case, obviously), so you can play comp if you want to run the risk. However, it’s probably in the best interest of yourself and others that you hold off on that until you eventually get a stable connection.
I mean, you don’t want your account perma banned from comp, and then a year later faster speeds are offered to your area, right? (Or faster speeds become affordable, in your case.)
Anyway! I don’t know your specific region or the rules that apply to your country, but something I did that you might can do is get involved on a community-wide scale.
I got petitions signed from locals requesting higher speeds for our area. I went door to door to collect signatures, directed them where to send emails and letters, gave them numbers to call, etc.
Get people involved.
Also, harrass the crap out of your locals ISPs. Call them every month checking on the status of plans for your area, etc. The goal isn’t to be annoying, but to be persistent.
My sister and I are literally the reason our area got DSL as quickly as it did. (And now we’ve moved up to cable and yay, everything’s almost up to speed with the rest of the world. XD) Point is, it doesn’t take an army - just one or two dedicated people.
If something like that is permitted in your country, I highly suggest you try it. Most people will sign a petition if you explain nicely, even if they don’t personally care one way or the other. Request faster speeds or fair pricing, or whatever is blocking you and your neighbors from having decent interwebz.
Good luck!
