Yeah, this has always been an issue with the game and was dramatically increased when they removed quick battle.
The amount of runes you get now are slightly more than necessary to level all new planewalkers up to 60. But what about every other PW that is not released in the current set? Do the dev's really want the players to grind story mode endlessly before they can use their PWs at optimal levels? This is the definition of making a fun game feel like a grind fest.
Some aren't opening their packs last I heard
My original message may have been misleading. Rune scarcity isn't a barrier to new players winning (see my recently updated profile picture), but it is a barrier to fun. For example, when you're starting it encourages you to fully level a single walker and then use the same walker for every PVE event, leading to unnecessarily repetitive game play. It punishes players for leveling mediocre walkers. My level 52 Gideon1 is essentially a waste of 45,000 runes. Because low- to mid-level planeswalkers typically have low-impact special abilities, it leads to similar game play across planeswalkers, more so than at high levels when planeswalkers are distinguished by access to unique and powerful abilities.I also fear that D3 might address rune scarcity for new players by rotating old planeswalkers out of standard, which seems a terrible solution to me. Just let players buy runes at a reasonable rate. That way they're available to newer players who are still rune strapped, but can continue to be ignored by established players that have huge numbers unspent.
