It's important to note that unit pool is shared across all players. That means, there are only a limited number of each unit within the total pot. What's important to realize about this, is the fact that it directly affects your ability to upgrade units. If multiple players have all picked a Bloodseeker in the first warm-up round, the liklihood of them then having the opportunity to ugprade them, is incredibly slim. Simply put, there will be too few for you to all reliably buy, meaning it'll take a long time - or be near impossible - to get the upgrades you need, without rotating what's available for purchase. Play such as this is not only gold intensive, but it's also like looking for a needle in a haystack.
If you're regularly seeing the same units on your store, it's because others aren't buying them and it would be wise - based on their abundance - to quickly adapt your draft to make use of the quick and plentiful upgrades you can obtain.
yeah im nearly 100% positive that its a shared pool
They basically took the concept of Go Fish! and turned it into a pvp game. And I really like it lol ---
