Visitor pattern is suitable for systems with relatively stable data structure and easy change of algorithm. Because visitor mode makes it easy to increase algorithm operation. If system data structure objects are easy to change and new data objects are often added, visitor mode is not suitable. The advantage of visitor mode is that it is easy to add operations, because adding operations means adding new visitors. Visitor mode centralizes the relevant behaviors into one visitor object, and its changes do not affect the system data structure. Its disadvantage is that it is difficult to add new data structures. -From Encyclopedia项羽有些意外，怎么今日的范增这样的通情达理，往日里可没见到亚父这样主动让自己去看虞姬？他们的关系一直都不是很好，这件事情一直让他有些苦恼。Comparing the panel injury formula with the actual combat second injury formula, We will find that the X% attack speed bonus affix on the weapon, the initial attack speed of the weapon itself, the accumulated attack speed bonus of peak equipment and skills will not affect the final scourge damage at all, but it is an important component of panel damage, which is why I said that some players' panel damage is inflated. Some BD, such as Shengguang Hammer, have useful attack speed, which directly affects the target gear level. At this time, the panel damage is not inflated. The Scourge Flow is precisely that the attack speed does not affect the release frequency of the Scourge (that is, it does not affect the gear of the Scourge. Although I did not test the release frequency of the Scourge under different attack speeds in the strict sense, the consensus reached from other players' experience posts, even if there is, has very little impact).比起实体书来，便宜不少。
