Regarding the matter of "should I replace Wu Zetian if I only have one Glory Crystal?", if you ask ten people, you may get different answers. Some people think that Wu Zetian is too weak, so it is not worth replacing. Others say that she is the most valuable after all. Heroes deserve a certain amount of respect.
In the past, Fingertips strongly opposed everyone switching to this hero. The reason is very simple. Wu Zetian's appearance rate has been low in several versions. It is not only because of its rarity, but also because of its low strength. Therefore, it is not worth playing. It is not recommended to switch. You have to endure it. The long skill forward swing and dead value make it uncomfortable to play.
If you don’t play it, you’ll feel like you’re at a loss, and if you play it, you’ll feel like it’s not very powerful, so it’s better to change the skin and at least use it with cards.
But with the passage of time, from the original "poor travel" to the current "rich travel", the mentality has also changed. In fact, everyone has the desire to collect. If you change the skin instead of Wu Zetian, your hero column will always be One is missing. Instead of worrying about whether Wu Zetian is fun or not and worrying about the incomplete hero pool, it is better to just replace it once and for all.
After all, there will be no more heroes online in the future. Buying Wu Zetian and collecting all the heroes also satisfies your desire to collect. This is actually the same mentality as having your favorite skin.
Fifteen heroes, fifteen collection skins, everyone's first choice must be different, because everyone's aesthetics are different, and the heroes they play are also different, naturally there is no so-called "optimal solution". The one is the optimal solution.
However, I can recommend a few representative skins to you for reference only.
The representative skin of hand feeling: Mingjian Yingying
This skin has already proven itself successful, and its initial reputation collapsed. However, as players learned more about it, they found that this skin is indeed a rare skin. Li Bai's Thousand-Year Fox and Phoenix Phoenix both feel good and were later released online. His poetry and swordsmanship are also at the top level, but Mingjian Yiying always has a place.
The combination of unique skills and characteristics, as well as numerous Easter eggs, make this skin a high-quality skin with the most details and excellent feel. Unfortunately, the strength of Li Bai's modern version is worrying, otherwise I would definitely recommend this skin.
Reputed representative skin: Infinite Hurricane
This skin has almost no negative reviews, and the experience of using and viewing it is completely different. The previous update added more handsome display actions to this skin, making it appear more advanced.
In addition to the particularly eye-catching design features of this skin (real mecha), the feel in the game is also very unique. Among Xiahoudun's many skins, the feel of Infinite Hurricane is unique, especially the second stage of skill 1, which is light and fluttery. The ground fell, but it felt as heavy as a stone.
Creative representative skin: Red Shadow Swift Front
Guan Yu's motorcycle skin went through many twists and turns before it was finally released. The creativity of this skin is subversive. It changed from a horse to a motorcycle, from a knife to a back knife, and from classical to modern times.
Because the design is too exaggerated, it has naturally caused some controversy. Some people say that the more such designs, the better. Others say that it is in contrast to the background setting of the hero. But no one can deny that this is a skin full of creativity. In addition, this skin feels quite good, as you can see from the fact that many KPL players like to use it.
The representative skin of dual forms: Silver Aria
There are many skins in the collection of skins with multiple forms, such as Xiao Qiao's Swan Dream, Cheng Yaojin's Vitality Assault, and Han Xin's Killing Shadows. Among them, his Swan Dream is relatively old and he simply changed his clothes. Yao Jin's Vitality Assault is a good idea, but there is nothing more than a slight change in image. Han Xin's Gun Killing Shadow only changes the color of the weapon and the special effects of his skills.
But the silver aria of the armor, three forms, changes the appearance, skills, sound effects, and even spell-casting actions. It is by far the best among the king's multi-form skins.
The above is just my personal opinion. Glory crystals are hard to come by. You must choose the one you like and don’t regret. After all, you can use it yourself.
