Most of the random eggs will be tier 0's, except the Ghost Mammoth, it should be easy to get multiples of these over a short period. Yes, the odds of getting the more common dinos through fusion is high, this is why you get a lot of the same ones; however, if you're only fusing duplicates there isn't really a lose to you.

Another thing to consider is that if coins are tight for you higher tier fusions can be quite expensive. Unless you're willing to spend crystals on dinos when they're released, fusion is the only alternative way to still get many other dinos.
