What I meant was the, main player built tiers, the rest are balanced out of those. We can build P tiers, but is intended as a build component with added benefit at reducing cpu and reactor consumption if used or was it weight reduction. Plus or minus tiers are only found either on the field or in the syndicate shop.
Anyhow, that makes my point even better, too many tiers. Maybe there is another way which I suggested some time back to reduce the clutter and thinking on the KISS principle, we could remove most modules and just have sliders to increase or decrease stats in robots.
Now, module would not need to be removed entirely, if not there would be little to trade or build, but if the devs want to move to a 'random module route' they could make bots more to be build in different parts, legs, torso, head and have just 3 module slots that each can increase or decrease the sliders maximum or minimum amounts of say dmg or cycle time. No need for so many slots or modules and tiers would be removed as the sliders provide the stats that players requires.
This also has an added benefit of new players finding the items they need on market, less items in the game would mean that keeping the market supplied by others would be easier.
