The bottom line, in my opinion, is that after establishing the concept in ME2 of Thanix cannons and them being powerful enough to even the odds against Reapers
Unfortunately you just making up stuff - all we learn is that Thanix cannons are more effective than our current guns, and that they are pretty good at taking out Collector cruisers. Without knowing anything about Reaper number and capabilities (if Thanix cannons give a frigate the firepower of a cruiser then you are still going to lose against an enemy with shields "impervious to dreadnought fire"), you cannot possibly make any deductions about the odds of winning a war.
Yes, not showing the Thanix cannons being used was lazy, but the war being unwinnable (despite Thanix cannons) does not technically contradict established lore.
And if you really want to go down that path then you should remember that it take much more than even odds to win a guerilla war because that is what we'd be facing if our forces were able to match the Reapers in a straight fight - basically, imagine Afghanistan if the Taliban were able to outrun bullets, teleport and had nukes.
I'm not making anything up. It took a lot of ships to take out a Reaper capital ship pre-Thanix. Then they reverse-engineered Sovereign's weaponry to create Thanix, which are far more powerful than the pre-Thanix ship weaponry. To say that DOESN'T even the odds is a fallacy.
No one, including me, is trying to imply that Thanix weaponry makes an Alliance dreadnought an equal to a Reaper capital ship, however, it does put them on much more even footing than they were pre-Thanix.
The problem is that their vision of ME3 required the state of the war to be like throwing rocks at a tank, and that's something that Thanix weaponry would have conflicted with, and that was my entire point, but if you want to miss the point, then go right ahead.
