Apparently comprehension is hard for some people. Let's assume that FF14's underyling architecture is totally sound and the only reason for lag is due to server proximity and/or the interval of pooling. In FF14 we know they pool every 0.3s. This creates some really nasty lag.

The speed of light travels 3000 km in 0.01 seconds, less than the distance from west coast to east coast. Therefore, assuming your game expect people playing across the coast, there would be no reason to pool data faster than once every 0.01s, because since it takes the speed of light 0.01s to even reach you, pooling the data any more frequent does not improve the lag factor. So we can treat all other MMORPG as pooling every 0.01s in an ideal case. If the distance/polling interval is the only factor, this means other MMORPG should exhibit the same behavior 3% of the time compaerd to FF14.

However, this overlooks the fact that if you're a PvP environment you will most definitely notice if an ability like Ice Block is failing the same way you failed to dodge a WotL. Even at a 3% frequency, factoring in the size of the MMORPGs and the time they've been around, and that PvP creates the 'failed to dodge WotL' situations with a very high frequency (except here it'd be your CDs failed to fire), the conclusion is that every MMORPG should've its PvP forum swamped with the same complaints about firing immunity abilities only to fail to work. Yet, this is not what people complain about in PvP games, suggesting that this issue doesn't exist in other MMORPGs. So, distance/polling interval cannot be the reason why FF14 lags especially bad, because even at 3% failure rate compared to FF14, no one would consider that acceptable for PvP.
