IMO Eye of the Storm Blitz map is the best blitz map. I think Blizz designed EOTS Blitz map that way to create a different type of battleground. EOTS Blitz is the only bg with multiple interlinked objectives.
You can think of BGB maps as falling into a few categories:
1. Cap the flag maps such as WSG
There are two objectives, and you need both to score. These maps are often decided by a few standout players, especially in relatively low MMR lobbies.
2. Resource control maps such as AB and Gilneas
Here you have multiple independent objectives. The outcome sometimes comes down to the weakest links on each team. For example, in AB someone ignoring his assigned role and rushing mid when teammates expect him to go mines, or in Gilneas a node sitter who doesn’t know how to spin.
3. Equal-contribution maps such as TOK
There are multiple independent objectives but you can work on all of them at the same time. Every player’s effort matters almost equally to the result.
4. Eye of the Storm Blitz
This is a completely new hybrid. It has three interlinked objectives that interact with each other.
To win, the team needs collective effort like winning the mid fight.
It also needs great individual plays, such as a skilled flag carrier surviving at high debuff stacks, a smart player forcing a flag cap while the enemy holds it, someone resetting the dropped flag to mid, or someone stealing a base while the enemy is distracted by the fight around the flag carrier.
At the same time, a single mistake from a bad player can cost the entire game.
In short, EOTS is a unique map that has interconnected objectives, reliance on team coordination, room for heroes to shine, and the risk of one weak link throwing everything away.
BTW, EOTS doesn’t punish unlucky class comps as hard as other maps. On most maps, if your team’s dps is significantly lower because of class comp, you’re screwed before the game even starts. Like if you got an Enh, a Sub and an Outlaw on your team, that hurts on some maps. But in EOTS, it really doesn’t matter.
