>>Problem is that /a/ refuses to talk about anime thats older then 5 years old
Patently untrue. /a/ has plenty of discussion about older manga and anime series that ended years ago. /a/ just also has a lot more new content to talk about than /co/ does. It's probably not easy to conceive of if /co/ is your main board and you don't spend any time at all on other more active boards, but /co/ has very little news or fresh content to discuss. The norm on /co/ is endless nostalgia circlejerks over years-old or even decades old cartoons and comics, because there's simply not very many new things to talk about. /a/ gets 60-ish new anime seasons every 3 months, with weekly episodes, hundreds of manga have new chapters every week. So virtually every single day there new anime episodes and new manga chapters to talk about. Every day. Even considering that /a/ doesn't talk about everything (certainly not manga, since only a tiny fraction of manga get translated), it means there's no shortage of new things to talk about.
Even despite all this, though, /a/ has lots of threads for older series. In recent years storytime threads have become ubiquitous on the board, which has kept older manga series fresh in the minds of younger posters, and then you also have perennial franchises that never die despite having no anime or manga content for years, sometimes decades.
