You'r eall missing something. The Tyranids have no reason to believe there isn't biomass in the Eye of Terror. Ignoring the fact that the Eye is not the warp, just a place where the materium and the immaterium overlap and actually has a large organic population (where do you think the chaos followers live when not fighting the Imperium?).

The tyranids are attracted to large concentrations of psychic presence. This is probably because of the psychic presence organics have. So they would have developed to associate large psychic presence with large quantities of biomass. The only psychic presence greater than the Eye of Terror is Terra. Since their early vanguard fleets realized the hard way that Terra is waaay too hard to attack, they likely would go for a staging point to gather huge amounts of biomass and then attack Terra. Given the association of psychic presence with biomass, the next best thing is the Eye of Terror. Hence, attacking the Eye of Terror makes perfect sense in several ways. Association of psychic presence to biomass, as a staging point, and possibly as a way to eliminate the competition for "food".

With the psychic shadow of a large Tyranid vanguard hive fleet (since the 'nids main fleets are drawing closer), it would, at the very least, disrupt Chaos enough for the Emperor to gain a decisive upper hand over them and close the rift that his throne seals. Then it's epic pwnage time delivered by his divine boot to some ugly ass.
