There are so many factors that can lead to the strength Of units first Griffins are Beast units  the strongest type of unit in the Game  And Archers are infantry the weakest  and first learned of the defense units. when you consider That Many more scrolls and much more resources and time  are required to learn Beast units . And they are the last units that can be learned in any Class of Troops that's Regular units ,Stone heart , Spirit units ,Vampiric units  and the Weorean's too Even the Dwarf units have the Beast units  learned Last . And throughout the Game the Beast units are the strongest of any given Class of unit in the Game  They cost more to Make  Take longer to Build and this has been the way it is  since the game started.

Different people have different Items activated and amounts Of Lost arts  learned also that will also cause a variance between players.  The  player with the most  upgrades to Champions , Crystal shards that can be activated, Lost arts and not to forget keep an eye on upgrading the obelisk of power improves over all. 

I guess  the saying you get more out of what you put more into  has a place within the answer to your Question. I'm sure I  may of missed something (Because there are so many reasons why different Players have a varied strength from others  but it will all will lead to upgrades upgrades upgrades  in every way is the best way to Optimize your units . I hope this answer Has been helpful. I'm sure there are many Players that will be able to fill in whatever gaps this answer may have :)

I have 1000 archers in a beacon when the brawl is on i get 49-52 points --I have a friend same league who has 1 archer and 1 griffin in beacon and gets 35-50 points how is his griffin as valuable as all my archers ty

You get points for how many of Bular units you kill. Not for defending the beacon. An archer has a base point of 20. So your 1000 Archers offer a base defense of 20 000 without boosts and defense offense counters. A Graffin has a base point of 300.  These stats differ according to boosts and levels. 

1 Graffin offers infantry defense that is equivalent to 90 archers,  occult defense that is equivalent to 50 archers, and a cavalry defense that is equivalent to 40 archers. 

In a group defense, your Graffin is 90 times more likely to kill an orc than your archer. 50 times more likely to kill an Ogre than your archer and 40 likely to kill an Orcish Rider than your archer. 

Remember in a brawl you earn points based on how many units you kill.

There is also a mechanism of the random slot, which was introduced with BG change. This system means that points are distributed not only according to the amount of defense you put in, but also evenly amongst all players in the defense party. 

I doubt that these scenarios you posted can play out. But if they do, it will likely be because of this. 

I agree with what moderator Wesley said...

I was under the impression that beacon points are distributed the same way that BG points are distributed. 

In battlegrounds, when Burlar attacks with a Beast heavy force and you defend with Beast, you get more points because you kill more of Bulars units. 

So I always thought if Bular attacks a beacon, and you are defending with the beast, you kill more beasts. and since bestiary are worth more points, you get more points. 
This has always been my understanding. If Bular attack with Infantry heavy, a person defending the beacon with more infantry gets more points. 

Bular force and type is also linked to dark essence. If Burlar attacks with more beast, you get more dark essence. If he attacks with more infantry you get less Dark Essence. This is because the amount of Dark essence received is dependent on the strength of the army, a beast heavy offence has more strength than an infantry heavy offence. 

I could be wrong. But I am glad that I learnt something.
