Thats why T1-2 guardians feels so harder compared to T3 around which players start building there engravings. It makes sense on other versions Guardian raids were the endgames and they slowly released probably big gaps between each levels. This is also why last guardian of every level is much harder as they were suppose to be the endgame boss of endgame. So you also had quite a few months between to build your engravings. But they dumped it all at same time without balancing anything and you get what we have now… a failed game mode.
The last T2 Guardian is one of the easiest in the whole game though
