Has there been a good war in shonen ever? Everytime there's a war arc it seems to suck the life out of the manga.
maybe FMA but other than that...
No. A war means tons of big characters on each side, which tends to just devolve into a bunch of meaningless match-ups. The only way to do a war arc properly is to riddle the landscape with blood and deaths of major characters, both of which are decisively "un-shonen". Hence why you see most shonens focus on "the few against the many" arcs instead.
Even FMA's final arc doesn't count because it wasn't a war, it was "few against the many" and secret missions galore.
