8th edition, rise of the lasgun

[The Madman]

Strength and Toughness are still in the game, And I highly doubt a Land Raider would be less then toughness 7, which is one point too high for a S3 lasgun to wound and also the toughness of a Dreadnought.

Strength and Toughness are still with us, and still use an opposing value principle (so much higher Strength will still wound on 2+, low Strength will wound on a 6+), and these aren’t capped at 10 any more either.

^That there debunks your assumption that basic weapons will rule the edition. A land raider (or any vehicle) can by toughness 10 or above, putting weapons like lasguns well without the boundaries of threats to such vehicles.

Here's a wound chart I threw together using the current one but extended to 20. I can see the current vehicles being between 7-15 in toughness and then have super heavies at 16-20 maybe more (it all depends if GW put a cap at all on stats)

The chart isn't perfect, as I would assume they may extend the 6+ to wound on the high strength weapons and change some of the 2+ to wound to 'auto' (I say if the S is X4+1 to the T, this means S5 auto wounds T1)
