Do roms become unstable after use?

[AC Question]

I have a galaxy s3, rooted. I am running Liquidsmooth rom for almost 8 months.
Just realised that its becoming quite unstable now. Frequent restarts, bad battery and stuff.
The battery has become horrible. It charges 4% per hour!!
Should I revert back to my stock rom or is there something else i can do?

Also, will going back to the stock rom help fix the battery problem?
