No, the reward actually is quite good, if You are the lucky one.

My best 3 cores earned 3000 INK over the last 5 hours (late starter), but my worst 6 cores did not get any block yet - and I canceled my AWS instances after 48 cores did not find any block in almost 3 hours

With that many orphans You need to be in the right place (+ good luck) to earn same coins - but the difficulty is still low....
