Not bad, better then most TCG just cause it has draft mode.

After ~100h in Legions I came to WG. Unlike Legions, you already have instant access (Practice) to try out all races (11) x 6 decks each (so 66 decks to play with no limits) which is super awesome, because in Legions it really took me a lot of time to see what few legions I like to play with, before even start to grind to about 85% of those complete decks. WG I treat as time-killer without pressure and wanting to repeat similar grind - if you think about it similarly, you can have fun with it. Game is free, very polished and faithfully reproduces w40k factions. Sure - it is pretty P2W if you really want to be competitive and move on fast - but at least you can try & explore it quite well, before decision if invest at all.

Apparently none of the negative reviewers have ever played a TCG before......
