I think having better defenses early on makes the game more enjoyable for everyone
That being said, wouldn't be better if the upcoming Armor and MR Stat Shards gave 7 Armor and 7 MR instead of just 5 Armor and 6 MR respectively? Decreasing the time to kill, specially on the early game where many games are decided, would definitely open more freedom since trading damage wouldn't be so risky, which allows more interactivity and response time.
Whatddya think?
Detail: It's good to remember too that 5 Armor has a gold value of =~ 100 G, while 6 AD has 210 G value, more than double of the gold value of the armor stat shard. I get that armor is stronger at early game, but that's still too much of a discrepancy.
